There are multiple * independent studies available on the web to confirm this story, with * FreeBSD, Solaris x86, etc... We have observed the following on two P6-200 (96MB memory, 14-disk (IBM DCHS) striped array, Intel EE Pro 100/B) connected via crossover cables: FreeBSD server - Windows NT client: 4.4MB/s FreeBSD server - FreeBSD client: >10MB/s That is the speed of ftp transfer of large files from disk to disk. (Of course, this could be the filesystem and not the network driver, but it's just a single datapoint anyway.) Satoshi
