Dean, That _will_ require some thought! Changing MaxTransfer to 512 _should_ slow things down. I did take a look at the read requests with TDebug while loading Mandril from DPaint and from UShow, and the requests are the same size, ie. there were a few 512 byte reads, but most were in the range of 5-17K per request. About the only thing I can think of is that somehow only 512 bytes are being used or transferred at a time, even though a larger number is requested, and that it goes back for each 512 byte block, requiring a re-seek. I can't for the life of me think of a way it could happen though, since it is not being done through a separate read request (or TDebug would (should?) pick it up). It's a puzzler. Played with a 2500 today. Ran Dpaint and Perfmon. Either they have fixed up some of the hogging of DPaint (it is a later rev than the one I have_, or the '020 is really humming. Perfmon would not 'max out' the idle graph when I clicked in the DPaint window. -larry
