Hi all,

I've tried over the weekend to optimise spam processing speed on this
box but with no major gains.

Here's some data that might be useful (jitter is my home box & newacorn
the not-yet-deployed production box).

Speed Logging

gmail => test => home

Spam Checks = no


11:12:31 Spam Checks completed at 43536 bytes per second


11:12:37 Spam Checks completed at 60548 bytes per second

Spam Checks = yes


11:15:17 Spam Checks completed at 491 bytes per second


11:15:26 Spam Checks completed at 1778 bytes per second

bonnie++ results:

Perl modules diff:

Let me know if any further info would be helpful.


Best regards,
