I installed the .163. Much better. When it spikes it's only for 500 ms. That I can live with.

Thanks.]]> Thu, 19 Jun 2003 12:40:00 +0000 https://www.logsat.com/spamfilter/forums/forum_posts.asp?TID=742&PID=1006&title=spamfilter-svc-spikes-cpu#1006 <![CDATA[Spamfilter Svc.

There is no virus checking software on this server. I'll look for your new beta build.

Incidently it would be nice to be able to turn off this automatic scanning and reloading after every 60 or 120 seconds. What would be nice is a feature that does a load whenever configuration is saved. And why is country information reloaded every 2 minutes or 1 minute?

We've seen cases where antivirus software (McAfee) would choke when scanning the SpamFilter/LogFiles directory. If you can try to exclude that directory from scanning you may get rid of the 1 minute spikes.

What is really odd are the spikes caused by refreshing the country stats. There's very little and fast calculations there, it should not bog down the server at all. The only thing we can think of is that our code does some calculations retrieving data from a graphic control rather than by storing data in memory (to save on RAM). This could in theory depend on the video card. It's a long shot, but we placed in memory this data now, so access times are faster. The new beta build 163 will be ready later tonite or tomorrow with this feature.

OK. I installed this version of the beta. Here are the results.

Every 1 minute spike to 90 % for a brief (1 sec) period. This is acceptable. Every two minutes spikes to a 100% for 15 seconds, this is bad. So it's loading the country stats that seems to be causing the problem. I am using the block by country feature.

We've uploaded  new beta that instead of running several task concurrently every minute (logfile saving, updating country stats, refreshing local black/white lists) spreads them apart (logfiles every minute, country stats every 2 minutes, local files refresh every 3 minutes). This should help us pinpoint the problem depending on when you are now seing the spikes.

I haven't timed it but it appears to be 5 to 15 seconds (I'll gather more accurate metrics).

For how long (milliseconds/seconds/minutes) does the SpamFilterSvc.exe process cause the CPU to stay at 100%?

How large are the sizes of your local black/white list files and keyword files?

We are running with 512Mb of RAM, typically we run around 150 to 200Mb's and only peak out at around 300Mb's.  Now that you mentioned Mcafee, it does shed light on a possible contributer to the spiking since we are also running Mcafee on-access scanning on the server.  A quick test with excluding the SpamFilter directory from being scanned for virus seems to have put the cpu spike at a much more expected level, a second or two per MB.  More observeration are in order of course.

Thanks,

-Jeff

How much memory do you have. I was running this version on a test server that was a Dual PPro200 with 256mb of ram and while it spiked on large multiple connections it never timed out.

I have since moved everything over to a Dual 1GB Xeon with 1.5 GB Memory and have not seen any spikes go over 60% (spikes only last a fraction of a second) and that is with 40+ connections with a 2,705 word count for a total of 17,959 characters. This server is also running IIS and Mcafee Net Shield along with ColdFusion Application server.

I would recommend more memory and more cpu power.
