OK, we are just getting ready to run some tests for this setup. SpamAssassin has some built in benchmarking that we will use. e.g. scan a set 500 spam messages, scan 5 sets using 5 different processes at the same time, scan 10 etc and measure time taken.
The applications make heavy use of perl and mysql as well as netio (numerous DNS lookups)
For FreeBSD tweaking, does anyone have any suggestions or requests what we should tweak or test to see how things perform ?
Anecdotal evidence shows us that AMD64, consistently runs at a higher load avg than the others, despite having an equal mix of spam thrown at it. One thing I am not sure of however is if this is truly slower (I suspect yes) or if there are differences in how load average is calculated on i386 vs AMD64 ?
