Now it filters spam effectively, but there seems to be a pause between each mail. The pause is perhaps 30 seconds long, taking forever to download and process 300+ mails
This sounds like a DNS blacklist timeout..
Try a quick test running an email through spamassassin -L.. if the 30 second pause goes away, check to make sure you don't have any dead DNS blacklists in your config.
In particular, 2.55 ships with support for the OSIRUSOFT blacklists, which are now dead. There's plenty of posts around detailing how to disable these lists, but these are the lines you need to add to your local.cf to do it:
score RCVD_IN_OSIRUSOFT_COM 0 score X_OSIRU_DUL 0 score X_OSIRU_DUL_FH 0 score X_OSIRU_OPEN_RELAY 0 score X_OSIRU_SPAM_SRC 0 score X_OSIRU_SPAMWARE_SITE 0
