I'm having problems reading multiple large files at once. Reading 100 1GB files at once. What happens is, when the buffer cache gets filled up, it all stalls, and transfer speed drops from 40-50 MB/s to a mere 2MB/s. This has been tested on all versions from 2.4.16-2.4.18-pre1. I've been testing Tux, Khttpd, apache 1.3.22, Apache 2, thttpd, cp and dd to verify the bug. Please help! roy -- Roy Sigurd Karlsbakk, MCSE, MCNE, CLS, LCA Computers are like air conditioners.
