hello,
i've seen this problem come up many times in the archives, and i've tried
lots of different options without success. i am using a win98 box to write
to a freebsd 4.0 samba 2.0.6 share.
i have tried all kinds of socket options, bigger send/recv windows, strict
sync is off. this is a 100baseTX full-duplex (switched) four-node LAN.
ftp write: about 4-5 megabytes/sec
samba read: around 4 megabytes/sec
samba write
from explorer shell: about 500k/sec
save from netscape of local file to share: about 1.2 megabytes/sec
none of these have been rigorous measurements, but it's clear to me that
something's wrong. copying a 30meg file should not take a minute and a
half on switched fast ether.
i have tried with/without the NODELAY and LOWDELAY stuff, set my buffers up
to values ranging from 8192 to 131072 (262144 fails with a no buffer space
available message) and generally tweaked until i turned blue. i've done
tcpdumps and i'm getting mostly full packets (1460 data bytes) and i didn't
notice anything wrong in the traces.
the poor explorer shell performance would point to strict sync, but it's
off. if anybody has any ideas, please let me know. my current (culled)
smb.conf follows.
