Still the performance is surprisingly low -- after changing the transfer width to 16 bits I ran the test on my dual P5MMX system equipped with an old ISA VGA card and I achieved 10.74ms for VGA RAM accesses and 586.6us for uncached main memory accesses. > by 1000 I get 3.4ms...

At least ServerWorks claims they are willing to cooperate with us although results seem to be questionable so far... Maciej -- + Maciej W.
