Looks like I have this issue again (pegging 4 core cpu) and resetting the process doesn't make a difference. Not sure what is causing it but it does slow down spam detection to 40-50 seconds for many emails. Any ideas what I can look at or do to resolve this?


Check the message sizes. As part of the newest spam storms we've noticed that a lot of the messages are huge (65536++). I suspect this might impact throughput as large buffers are allocated and moved around to handle these messages. This kind of thing has also been known to cause NTFS to crawl.

Please let us know what you find.

If you are not already doing it -- you should consider blocking connections using the truncate blacklist. No sense taking on some of these messages if they can be eliminated up front.
