Hi Dylan, First, a small overhead is something you should expect, due to the time needed to scan the messages. Of course "small" is very dependent upon your hardware specs, your configuration, the size and type of the messages, etc. So it could be that your current hardware/sowtware setup is not powerful enough to cope with the messages flow. I doubt that's your problem, but, just in case, how's the load on the box? Secondly, it could be that you've enabled some potentially time consuming config option like MailFollowURLs or one of the archive related option... I'd start from there... Another option is that some of the messages are just HUGE and clamd takes a lot to process them. Finally, it's (maybe?) possible that some message is causing clamd to infloop which prevents your queue from flushing again. If that's the case please file a bug report to bugs_at_clamav.net (remember to encrypt the message with gpg or zip). So, well... "Clamd is slow" doesn't really give out enough clues to help you. Please investigate the problem a bit further and see if you can come up with something. -aCaB _______________________________________________ http://lurker.clamav.net/list/clamav-users.html
