spambench

[Nicholas Clark <nick@ccl4.org>]

I'm trying to see if I can use spamassassin as a benchmark for core tweaks

Good news: It seems to generate timings which are slightly above noise level.

For scanning 26 SOBIG.Fs:

$ time /usr/local/perl20854/bin/perl5.9.0-cow spamd/spamd -x -p 47373 -C rules --siteconfigpath t/log/localrules.tmp -L

real    3m6.281s
user    0m15.140s
sys     0m5.430s

$ time /usr/local/perl20854/bin/perl5.9.0 spamd/spamd -x -p 47373 -C rules --siteconfigpath t/log/localrules.tmp -L

real    0m36.344s
user    0m14.620s
sys     0m5.530s

(ignore the real time, because I didn't start spamc for a while)

Bad news: Which I think means that COW is 2% slower than no COW. At least
according to this metric. Maybe I should feed it more regular spam. I've
got enough.
