I can tell you right now, its either Net tests or poorly written

Darn good is how good ? 
On a Dual Xeon with 4GB ram can SA scan 30k mails per hour. 
Today at 15k the machine starts signalling problems , 20k is the max it
can do beyond which there are unacceptable delays 

Spammassassin -D --lint < some_test_email

How do I know what percentage of time is taken by individual tests ? 

Try installing mailwatch in a limited manner (mailwatch.sf.net, works 
only with mailscanner), you do not have to use it for quarantine 
management or any other thing.. under tools you have a link for a lint 
test which gives you nicely formatted html page with the time taken for 
each test.

As Chris mentioned.. network tests (especially razor/pyzor) could be 
responsible for SA delay. If you have a lot of servers try running a 
local only pyzord (see pyzor.sf.net).
