The other thing that bothers me is, that under freebsd is quite easy
to get:
[send_ip] sendto: No buffer space available
It happens almost always on my laptop just few seconds after I start
hping with timecounter=TSC
I'm not sure, but from what I understood of Robert Watson's
explanation in the big ZFS thread on -current, maybe increasing
kmem_size (exactly as for ZFS...) could help you with these buffers.
Is this not just running out of mbufs? netstat -m will show if it is
and the fix
is to just increase kern.ipc.nmbclusters.
670/1520/2190 mbufs in use (current/cache/total)
462/322/784/25600 mbuf clusters in use (current/cache/total/max)
462/306 mbuf+clusters out of packet secondary zone in use (current/cache)
0/35/35/12800 4k (page size) jumbo clusters in use
(current/cache/total/max)
0/0/0/6400 9k jumbo clusters in use (current/cache/total/max)
0/0/0/3200 16k jumbo clusters in use (current/cache/total/max)
1091K/1164K/2255K 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)
0/4/6656 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
kern.ipc.nmbclusters: 25600
sysctl -a kern.ipc.maxsockbuf ?
No, this doesn't change things.
with timecounter=TSC it's easily reproduced on on 6.3.
