The configuration used: lab2 prodo thrallo Pentium/200 Xylan OmniSwitch 9 Axil 320 (2x75Mhz SuperSPARC) FreebSD 2.2.6-R XOS 2.1.7 RELEASE Solaris 2.5 fxp0 ------------ FESM-8 100Base-TX ---- Sun HME 100Base-TX Ftp results, using a 6 MB binary file: FreeBSD client, Solaris server: put: 6043820 bytes sent in 10.57 seconds (558.58 KB/s) get: 6043820 bytes received in 6.19 seconds (953.43 KB/s) Solaris client, FreeBSD server: put: 6043820 bytes sent in 6.5 seconds (9.1e+02 Kbytes/s) get: 6043820 bytes received in 5.7 seconds (1e+03 Kbytes/s) Note the OmniSwitch was not exactly quite, but wasn't heavily loaded either. You *can't* load an Omni with the 20 people we have in our office here. ;^) The FreeBSD write performance isn't stellar, but I'd say your problems may have something to do with the switch. I can probably work you a deal on a nice shiny new OmniStack 1032! ;^) -- "Where am I, and what am I doing in this handbasket?"
