Why can't FreeBSD match the read performence of the sun? ;) Because your FreeBSD machine has a poor network card (or poor FreeBSD driver)? I've tested it with a ~ 20 MB file mounting localhost. I've got 14 seconds reading the file, ~ 1458 KB/s. This is on a not-so-fast 486/33. Since i know that it's possible to saturate an ethernet with FreeBSD (network data rate > 1 MB/s), i suspect your ethernet card is the bottleneck. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
