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.
