Try to get local copies of the DNSBLs. Run a local caching server
for those you can't get fully locally. Reject more spam based on
SMTP violations like earlytalk or HELO syntax. Do greylisting.
Check your spamd box isn't running out of RAM. Outsource your
antispam. :)

Not really because later tests may provide a negative score which
would bring you down below the threshold, thus by using
shortcircuiting you will classify a higher percentage of legitimate
email as spam.
