Please, I need some feedback (good or bad) about using a CD-ROM cache software utility. I have been looking at the Lightning package from Lucid. Also, I believe Speedway does the same thing and there may be others. So, is this just a second cache that will co-reside with SMARTDRV, for example? How well does it integrate with memory management, etc. Personally, I think PC configurations are getting too complex but if you need this for a decent performance then I guess that speaks for itself.

There is a new caching program about to be put on the market that is incredible. I forget the company name that created it, but Symantec just bought all of the marketing rights for it. I suspect it will flood the market in a week or so. It is a disk caching program, which has extensions for CD-ROM. In my tests it blew away CD-SPEEDWAY and every other caching program I have used. We tested a beta copy while working on The New Bible Library CD-ROM. The software is called SPEEDCAHE+. I highly recommend it.

I've been using SpeedCache+ for a couple months now and it's worked great. It'll cache just about anything including CD-ROM drives (it replaces your existing disk cache). Yes, Symantec bought the product about 3 months ago and is selling it for $19 to registered owners of Norton Utilities. That's how I got mine. I've only found one problem with it. When caching floppy drives, it doesn't always notice when a floppy's been changed in a drive when running under Windows (no problems when running outside of Windows). Thus, I have to temporarily disable floppy drive caching when I'm installing a multi-disk Windows program. Larry

how does it do with cdrom games like 7th Guest?
#48853From: Robert (Sandy) SandhausMay 20, 1993 2:58 PM
I've been using Speedcache+ as well and have 7th Guest. There is essentially no speedup, as you'd expect, the first time you view a scene, but as you move around, you often repeat a previous scene and these movements are spead-up nicely. Seems to be a great program. Only way I could see a better cache for a CD-ROM would be to have 650 Mb of RAM committed to the cache or have a program that could read your mind and know which parts of the disc to cache ahead of time!

Steve, A CD-ROM cache is not going to help much with The 7th Guest unless you can allocate 10meg+ of memory to the cache and even that would probably have little effect. T7G is consistently sending a large volume of data from the CD-ROM to the PC for its graphics effects and unless you bounce back and forth between two locations, you'll see little benefit. Larry

thanks for the response, Larry. I just finished the game last night. Pretty hard towards the end! Never did solve the microscope puzzle. That was the only one I cheated on. How about you?

You mentioned that you must dedicate 10meg+ of memory to the cache to get any gain in performance when running 7th Guest. There is a CD-ROM cache, called CacheAll, that takes caching one step beyond other CD-ROM cache programs. CacheAll allows you to allocate memory and hard drive space for the cache. Since your hard drive is still MUCH faster than the CD-ROM, you will still get some big performance boosts even if you don't have the memory to dedicate to the cache. For example, you can setup a 2 mb RAM cache along with a 10mb or 15mb swap file. When the RAM part of the cache fills up, it will push stuff onto the hard drive. When you attempt to read information from the CD-ROM drive it will first check the memory cache, then the swap file, then the CD-ROM drive. If you want to download an evaluation version, it is available in the DOS, Windows, OS/2 library with the filename CAV10D.ZIP. Dave

David — Well, yes — but the experience of at least some of us here with the evaluation copy of cacheall was pretty bad — lots of good ideas, but the major effect was to hang my computer. Use Cacheall with extreme caution, and back up your hard drive — just in case <g> Craig
#49376From: David FinkelsteinMay 27, 1993 11:23 PM
Craig, If you give me your address, I will send you an updated version of CacheAll (1.0f). A few people did report some problems of CacheAll hanging their machine, but many people also found it to work very well. Of the machines that did not "like" CacheAll very much, we were able to resolve all the problems. Thanks, Dave
#49384From: John M. Delaney, JrMay 28, 1993 1:57 AM
Hi dave…I just downloaded CACHE ALL Ver 2.0e from the BBS, and installed it on my 486 33mhz clone…and it finally worked, but when I tried to go to windows…it just hung up forever… How can I get the latest copy? Thanks
#49418From: Craig HenriksonMay 28, 1993 8:07 PM
David — Sure- I'll give it a try again. Craig Henrikson 37 Herrick Ave. Delmar, NY 12054 Thanks Craig
#49956From: Doyle PitmanJun 5, 1993 10:15 PM
David, Would you also send me an updated version of CacheAll? As a CD-Rom Player user (NEC MultiSpin External – CDR Series) and a sysop I'll give it an evaluation and upload it to my board, The FileBase BBS!, CA (818) 891-3458, and to other _larger_ bbs in the San Fernando Valley (outside Los Angeles) area. Send _any_ size diskette to: Doyle Pitman PO Box 8529 Universal City, CA 91608-0529 If you prefer to call the board… (up to 14,400 bps) leave me a message by (from the Main Menu) hitting M for message section and E for Enter a message… and send to 000 conference to DOYLE PITMAN. We are using the latest version of WildCat! BBS software. Thanks, -=Doyle=- P/S, We do, at present, have CAV10D.ZIP on the bbs.

Today I got a CD with a benchmark test on it and tried it both with & without Cacheall. I got better results by not using Cacheall! I even had it set up like it said to — cacheing the CD to HD and the HDs to RAM….. Oh well… Oh, I also felt it took up too much space in my conventional RAM. Something like 56K!
#49377From: David FinkelsteinMay 27, 1993 11:26 PM
Scott, If you have EMS memory available, CacheAll will only take 21Kb. Could you let me know the name of the CD with the benchmark software on it? I would like to let our technical guys run some tests to see if we can reproduce this scenario. We have tested with the MPC Wizard and found CacheAll to improve the speed by over 2000%. Also, the latest version of CacheAll, 1.0f, has just about doubled in speed. Thanks, Dave
#49381From: Scott BoydMay 28, 1993 1:04 AM
No, I don't have any EMS mem available. Only have a total of 5 Meg RAM, use the upper 4 Meg as extended. I run Windows alot, it likes extended better. The CD is called: MegaDemo 1 from : Profit Press 2956 N. Campbell Ave. Tucson, AZ 85719 Info: (602) 577-9696 Fax: (602) 577-9624 Orders:(800) 843-7990 They have some shareware CD's and such. The ad was from –Windows Sources– and they have a special prices now (how long – ?) You can get the MegaDemo disk with CD test and abt 350 meg of Shareware/P.D. software for $14 + $6 S&H, OR at the cheapest – buy their Mega CD-ROM1 CD for $25 total & get the Demo disk free. That's what I did, was get 2 disks for $25. The demo CD has mostly software that is on Mega CD_ROM1. They also have a MegaCD_ROM2 that is $35 total that's supposed to be mostly newer stuff. BTW, the Mega CD_ROM 1 was full – 650 Meg. The Test & benchmark is fairly good, only takes a few minutes. The MPC Wizard said my data transfer rate was something like 58k/second, this other test gave me 92k/second, which to me sounded more realistic. I had some other used CD_ROM drives that I tested. A hitachi CDR-3700, with a 64k buffer, got the score of 154k/second data transfer rate. That sounds about par for a medium-priced CD-ROM drive made in late 1991. So I now have the CDR-3700 in my machine and I sold my CDR-3600 (32k Buffer). I wasn't able to run MPC wizard on the 3700, as I had only borrowed the CD from a friend, and gave it back before I got the faster drive. Hope this gives you the info you were looking for! Oh, BTW, I can upload a report on the benchmark test for my drive if you would like to see what it prints out, if you'd like. It's just a small text file. Scott
#49518From: steve pyeMay 30, 1993 6:56 PM
have you uploaded the newest version anywhere? I'd like to give it a try. thanks. steve
#49957From: Doyle PitmanJun 5, 1993 10:15 PM
David, DF>> We have tested with the MPC Wizard and found CacheAll to improve DF>> the speed by over 2000%. I'm not aware of any shareware benchmark testing for CD-ROM Players… with the exception of one I tried (that I can't recall the name of that DIDN'T WORK!). Could you give me the name of one? Is MPC Wizard a shareware program? If so, do you know were it is available here on CIS, what the size is, and what the EXACT filename is? Thanks again, -=Doyle=-
#48857From: Larry LandMay 20, 1993 5:30 PM
Larry…How easy is it to disable devices like floppies? Can it be done on the fly? Thanks. -Larry
#49079From: Larry SchneiderMay 24, 1993 10:55 AM
Larry, Very easy to disable floppies and it can be done on the fly…I do it all the time, especially in Windows. Larry
#49109From: Larry LandMay 24, 1993 5:41 PM
Larry…Thanks for the info. I'm not really sure I need a CD cache since I just bought a double speed drive. Be seeing you. -Larry
#49175From: Larry SchneiderMay 25, 1993 9:47 AM
Larry, I own a double speed drive (the NEC CDR-74) and as fast as it is, it's still a heck of a lot slower than a disk cache. I felt that Norton SpeedCache+ was a terrific value at only $19. LS
#49192From: Larry LandMay 25, 1993 5:14 PM
Larry…That's good to know. I'll put the cache on my wish list. Be seeing you. -Larry
#48848From: Steve SolomonMay 20, 1993 1:18 PM
I have tried both the CD Speedway program, and the Lightwin package. I can honestly say that I have never hated 2 programs more than these cache programs. The documentation absolutely sucks with cdspeedway. And both programs actually slow things down if you are using cds that don't go back for the same information. This is because the cache program will cache as much as it can to the hard drive or ramdisk, and then use that info if it can. I know that when I used either program with my Nautilus disks, it took about 1 minute more to load the opening screen, and then after that about 25% longer for everthing else. The exception to that was when I returned to the last item, it was right there with little or no wait. So, now you have one opinion!
#48870From: Joseph CarchidiMay 20, 1993 8:19 PM
Interesting coments I knew this was not going to be a breeze. Couple of things: Regards the Norton cache, does the new one replace NCACHE? Does it come packaged with the NU 7.0 utilities? Does it do anything special, knowing that there is has a CD-ROM drive to cache, like CD Speedway which claims to use your hard drive as a secondary cache when memory gets full. Steeve, I would be interested in how much memory you have since, to be fair, that one variable could be key to the CD Speedway product to work well. How about tweaking the software. Anything to explore there? Recently, I have tried the new Netroom 3 memory manager from Helix. They have a very daring new technology that is far ahead, in theory, from the competition. What they do is provide a technique called 'cloaking' where they run certain utilities in 32 bit protected mode in extended memory. They run faster and one of the utilities is a Hard and Floppy Disk cache. It really works great. They still have a few kinks to work out and when release 3.1 hits the stores this summer, I'm getting it based on the results of my tests. I have been checking their forum here on CS and many users are demanding a CD-ROM cache. That will complete the deal for me!!!
#48975From: John M. Delaney, JrMay 22, 1993 10:19 AM
I had been using SpeedCache+ but when I added MS-DOS 6.0 it wouldn't work anymore…so now I'm using NCACHE by Norton in Norton Utilities 7 but it doesn't cache the CD-ROM… How do we get an updated SpeedCache+ if symantic bought it?
#49026From: Joseph CarchidiMay 23, 1993 12:12 PM
John, I am convinced that the new cloaked (32 bit code) disk cache from Helix software's new Netroom 3 will support CD-ROMs in a future upgrade because the thing is the fastest disk cache I've ever tried and their users are beating the doors down for a CD-ROM cache inclusion. I'm keeping my fingers crossed. This could be Nirvana!
#49045From: John M. Delaney, JrMay 23, 1993 9:46 PM
Really… Gosh, I don't think I have heard or seen this! Let me know if it does do CD-ROMS's… Thanks
#48886From: Rich Bowers/OPAMay 20, 1993 11:10 PM
Steve: PMJI, but doesn't it make some sense that caching might work less well with a product like Nautilus? In Nautilus, you are looking at a lot of relatively short, but distinct pieces. In other programs, you have longer sequences of data that the program can get ahead of, on the simple prediction that once you start a sequence, you are likely to continue it. Were you able to try either of these programs on other CDOMs of a different type? Best – Rich Bowers
#48921From: Steve SolomonMay 21, 1993 12:45 PM
yes, I did try the cd cace programs onc Coreldrw (cd based version), Multi Media Beethoven, Bookshelf, as well as Nautilus and the new game 7th Guest. I still hate the product! Wish they could improve them, so we could actually use them!
