As Michael said , no errors! Where do you see the out of memory? In terms of the JMX, the likely culprit is probably the HTTP cache manager. I see that it clears after interation but I also see each iteration apppears to download a hell of a lot! I haven't counted at all, but I imagine a worst case scenario of 128 threads running simulateanously and downloading say 10mb per iteration, theres up 1.2Gb memory gone before you even count jmeter's own memory usage.... have u tried running without this element?

Are you doing anything odd in your thread groups that might consume a lot of memory? If you want to share ur JMX file i can take a look and see if I can spot anything.... Regards, Adrian -----Original Message----- From: Eric Tchepannou [mailto: [EMAIL PROTECTED] Sent: 13 August 2008 17:58 To: JMeter Users List Subject: OutOfMemoryErrors. Tips for performance improvement. Hi all, I am looking for tips to improve performance with jmeter. I have recorded a web test script containing two thread groups. Following the jmeter's best practice guide, I have disabled all my listeners and I am running in nongui mode and with "-Xms2048m -Xmx2048m". I am trying to simulate 128 (2 x 64) users for one hour, but constantly get OutOfMemory errors after about 15 minutes. I would have hoped to be able to perform this test from a single client, but it looks like this will only work with distributed testing or do you know any other useful tip I could use to improve the performance? Thanks, Eric. ************************ This message has been delivered to the Internet by the Revenue Internet e-mail service (OP) ************************* --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] ************************ This message has been delivered to the Internet by the Revenue Internet e-mail service (OP) *************************
