Hi
Here goes for a first post.
I run an mldonkey server under 4.10-STABLE (though I noticed the same
behaviour under 4.8 and 4.9). It also runs samba and ssh2 all on a
p2-333.
Generally what happens is I download files to this fbsd server and
share them to my other pc via samba. When first rebooted this
works fine with full ethernet copy speeds.
After a while copying files from the fbsd box to the pc rate limits
to 40k (via smb/ftp/ssh2 whichever) over the ethernet lan. This is on
100mbit cards I've tried different cables/cards/switches etc with no luck.
I'm guessing there is some memory/network/file descriptor limit I'm
hitting and I've no idea how to extend it or clear it.
I've made the following mods in sysctl.conf
kern.maxfiles=65000
kern.maxfilesperproc=65000
kern.ipc.somaxconn=4096
kern.ipc.maxsockbuf=1048576
net.inet.ip.fw.verbose_limit=0
and in kernconf
machine i386
cpu I686_CPU
maxusers 512
options NMBCLUSTERS=16384
options NMBUFS=32768
sample output from netstat -m
149/944/32768 mbufs in use (current/peak/max):
101 mbufs allocated to data
48 mbufs allocated to packet headers
73/348/16384 mbuf clusters in use (current/peak/max)
932 Kbytes allocated to network (2% of mb_map in use)
0 requests for memory denied
0 requests for memory delayed
0 calls to protocol drain routines
# netstat -an | grep tcp4 | wc -l

Does anybody have any suggestions or ideas as to optimize this or
have I hit some limit that can't be exceeded?
thanks again,
Joe
