Hi, I have a Solaris Workstation Ultra 1 170Mhz and a FreeBSD server Pentium Pro 200Mhz, w/ 2940 SCSI and vx0 ethernet interface manually set to 100 Mbps, on a 100 Mbps LAN. Last week (maybe since upgrading 2.2.5 Stable from december to 2.2.6 BETA, beginning of March) I have experenced bad network performance between the two. Here's an ftp transer of on huge file from Sun to Freebsd 2.2.6 BETA: 12621935 bytes sent in 1.3e+02 seconds (95 Kbytes/s) Here's the same file ftp'd from the Sun machine to a 2.2.2-stable pentium on the same LAN but running 10 mbps (we have a 100 mbps hub with a downlink). 12621935 bytes sent in 13 seconds (9.6e+02 Kbytes/s) Better... Really good, I'd say ;-) Now, I try from 2.2.2 to 2.2.6 BETA: 12621935 bytes sent in 13.76 seconds (895.56 Kbytes/s) Also quite alright. So, what can this be? It happens on nfs, ftp, amanda, you name it, so it seems like it's the tcp/ip or ethernet stuff somehow. This is beyond my level. One thing I'm supecting is that I don't use full duplex with the ethernet card on the 2.2.6 server since this crashed the machine while booting; I had to manually set it to half duples (simplex?). Haven't tried resetting this, but I will as soon as I can take it down. /Palle > ifconfig -a vx0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 inet 193.219.246.210 netmask 0xffffffc0 broadcast 193.219.246.255 atalk 65280.91 range 0-65534 phase 2 broadcast 0.255 ether 00:60:97:9a:b4:a6 rc.conf has tcp_extensions="YES" # Allow RFC1323 & RFC1644 extensions (or NO). for what it is worth... ftp> get ie4setup local: ie4setup remote: ie4setup 200 PORT command successful. 150 ASCII data connection for ie4setup (193.219.246.210,40048) (12621935 bytes). 226 ASCII Transfer complete. 12660165 bytes received in 167.10 seconds (73.99 KB/s) ftp> put ie4setup local: ie4setup remote: ie4setup 200 PORT command successful. 150 ASCII data connection for ie4setup (193.219.246.210,40049). 100% |*******************************************************| 12363 KB --:-- ETA 226 Transfer complete. 12659956 bytes sent in 10.33 seconds (1.17 MB/s) BTW, the huge file is m$ internet explorer for solaris, which throws me out of my CDE session and kills all apps immediately each time I try it.
