That version of SpamAssassin is quite old.

I gather that you have read
http://wiki.apache.org/spamassassin/FasterPerformance The large
local rules file will affect performance. If you want to keep pyzor
and razor2, see http://wiki.apache.org/spamassassin/UsingNetworkTests
on how to reduce the timeout values. Run spamd with the -D switch to
find out whether there are any errors.
