[FUG-BR] RES: freebsd 8.2 - tuning de rede

[kmkz bleh]

Outra coisa que estou vendo, é que além dos pacotes perdidos, ainda tenho

ping: sendto: No buffer space available

Mas já aumentei muito o kern.ipc.nmbclusters (no momento deixei 4194304).

gw-ija# netstat -nm
6521/3724/10245 mbufs in use (current/cache/total)
6517/3713/10230/4194304 mbuf clusters in use (current/cache/total/max)
*6516/2956 mbuf+clusters out of packet secondary zone in use (current/cache)

0/0/0/3200 16k jumbo clusters in use (current/cache/total/max)
14688K/8357K/23045K bytes allocated to network (current/cache/total)
0/0/0 requests for mbufs denied (mbufs/clusters/mbuf+clusters)
0/0/0 requests for jumbo clusters denied (4k/9k/16k)
0/6/6656 sfbufs in use (current/peak/max)
0 requests for sfbufs denied
0 requests for sfbufs delayed
0 requests for I/O initiated by sendfile
0 calls to protocol drain routines

Mas não esta fazendo efeito...
