Hi,
No sollution, but a "same here". I've had similar behavour on my setup:
sendmail+clamav+sa.
When running MS and SA in debug mode, I noticed that around 50% to 80% of the
processing time was spent on obtaining a lock on the bayes database.
My setup:
debian unstable, kernel 2.6.5
sendmail-8.12.11
MailScanner-4.30.3
clamav-0.71
spamassassin-2.63
Max SpamAssassin Size = 30000
Max Unscanned Bytes Per Scan = 100000000
Max Unsafe Bytes Per Scan = 50000000
Max Unscanned Messages Per Scan = 40
Max Unsafe Messages Per Scan = 40
Max Normal Queue Size = 2000
Bayes magic:
0.000 0 2 0 non-token data: bayes db version
0.000 0 163094 0 non-token data: nspam
0.000 0 13224 0 non-token data: nham
0.000 0 435207 0 non-token data: ntokens
0.000 0 1084290758 0 non-token data: oldest atime
0.000 0 1085525323 0 non-token data: newest atime
0.000 0 1085525334 0 non-token data: last journal sync atime
0.000 0 1084784968 0 non-token data: last expiry atime
0.000 0 345600 0 non-token data: last expire atime delta
0.000 0 189064 0 non-token data: last expire reduction count
Would putting the bayes dirs in tmpfs increase the speed of the locking of the
bayes-databases by SA?

Eelco
