Hi All We are experiencing a problem on our production server which is running Cold Fusion MX 6.1 (Standard stand alone installation) Apache 2.0.40 PostgreSQL 7.4.1 JDBC Driver 7.4 Build 1 ( JDBC3 ) The hardware is a beefy dell server not 100% sure on the specs but dual > 2GHz CPU, > 1Gb RAM plenty of disk space The site generally runs really well and using Microsoft Application Center Test can test it handling 300+ requests per second. The problem is that during these tests and at any time the site say at 40 second intervals will take up 20 seconds to return a request. after this 20 second interval the site takes off again to its maximum performance for about 40 seconds and then cycles like that indefinitely. The request will always be returned though. The interval of slowness changes when we decrease the number of hits but perplexing it actually gets shorter rather than longer. Hitting a simple "hello world cfm page" exhibits the same results but hitting a html page doesn't. Remember this site is live during these tests so it is possible and highly likely that CF is still dealing with Postgres through other requests. On our dev box running the same software but only a dual Pentium II 400MHz with 500Mb Ram the site constantly returns 200+ requests per minute with no real performance spikes to think of. One thing to note is that during these performance dips on the production box one of the cpu's is used up at 100% by the CF Process and the other(s) aren't doing much at all and the RAM is has 100's Mb in reserve. CF Cache template setting is set at about 10 times more that the actual templates in the site.
Any ideas would help Cheers Shane ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Special thanks to the CF Community Suite Gold Sponsor - CFHosting.net http://www.cfhosting.net Message: http://www.houseoffusion.com/lists.cfm/link=i:14:3745 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/14 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:14 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.14 Donations & Support: http://www.houseoffusion.com/tiny.cfm/54
