One of the potential reasons for listener sluggishness is the listener is maintaining a log file to which it is appending all the time. Most people don't care to just delete the log file occasionally and will end up with a log file of a few hundred megabytes.
I would recommend investigating this issue first, before trying to implement such radical measures.
Talking about radical, you seem usually to post to many, many newsgroups. Could you *please* refrain from that, there's no need for it and you are wasting bandwith.
