looks like there is improvement. 507>488.
but i know what you mean. why is this not a big number who makes you
feel good?
first, make sure kern.usercrypto=1
second, vmstat(8) says that '-i' tells you interrupts since system
startup. since there is no other info given, i believe rate is also
going to be a rolling rate since system startup.
line 773 of /usr/src/usr.bin/vmstat/vmstat.c:
---
if (cnt || zflag)
(void)printf("%-16.16s %20llu %8llu\n", intrname,
cnt, cnt / uptime);
inttotal += cnt;
---
so if i'm at the right spot, it is a rolling average.
watch 'systat vmstat' and you'll see interrupts per display-interval
( or second, don't remember which ). this is not as easily greppable
tho. i don't know of a better way, but am interested in being told :P

ps, fwiw, here are some SCPs from a 4801+1401 to a 2x.k7-MP+1401, of
a 32MB file from dd if=/dev/arandom. both machines are 3.8 current
from aug.29 snapshot, and neither was doing much of anything during
the "test":
for i in aes{128,192,256}-{cbc,ctr} arcfour{,128,256} 3des-cbc; {
echo $i
scp -c $i arandom.32M arandom.32M arandom.32M telperion:/MNT/warthog;
