You most probably are using bayes filtering. This is controlled by the 
"use_bayes" directive in your spamassassin (not amavis) configuration.

Furthermore, you have auto_expire enabled (think of expiration as a 
"periodic cleanup" that spamassassin must do to the bayes database). 
This is known to cause large delays.

You can disable auto-expiration by adding "bayes_auto_expire 0" to your 
spamassassin configuration.

Then perform an expiration periodically in a cron file (make sure it 
runs under the same user amavis is running). Expirations are triggered 
through sa-learn (again, make sure you run that under the same user 
amavis is running):

   sa-learn --force-expire
