appendix K of the report contains the configuration changes
and one code change that they (the polyteam) made to their FreeBSD
machines. interesting reading.
kernel config:
options "MAXDSIZ=(512*1024*1024)"
options "DFLDSIZ=(128*1024*1024)"
options "NMBCLUSTERS=40960" !!
options TCP_ACK_HACK
/sys/conf/param.c
#define MAXFILES (16384)
int maxfilesperproc = 12288
/sys/netinet/tcp_timer.h
#define TCPTC_MSL (3*PR_SLOWHZ)
/sys/kern/uipc_socket.c: (faked diff)
if (resid >= MINCLSIZE) {
MCLGET(m, M_WAIT);
if ((m->m_flags & M_EXT) == 0)
goto nopages;
mlen = MCLBYTES;
len = min(min(mlen, resid), space);
} else {
+ atomic = 1;
nopages:
and there is more, take a look at
