I got a problem with snapshot (not shure if it's the last),
download is really slow, 0.3 to 1 Mbps per customent.
Also a lot of paquet lost beginning from the openbsd.
The're around 800 to 1000 users on this server.
Bandwith is not a problem but we often saw limitation in number
of paquets be the problem on our old servers. When it's happen
with linux, it often a ct sysctl value. I saw this too with PF on
FreeBSD that I add to give higher value in set limit.
I use the same limit value than on my FreeBSD server that have 3 x more
traffic and users.
set limit { states 196608, src-nodes 16384, frags 8192, tables 1024,
table-entries 131072 }
so I really don't think those value are too low

no queue and I don't see any error in dmesg or in the log. CPU load is
between 4 to 8% load checking with systat, 1920704 active memory free.
Interrupts total from 6 to 7k.
Is there a sysctl that could block too much connexion ? I looked at the inet
list 1 by 1 but didn't find anything for now. Any other idea ?
