Re: Tomcat benchmark
Hi Andrew You can determine the number of concurrent requests using sample formula This formula gives a decent estimate for the number of threads you can create: (MaxProcessMemory - JVMMemory - ReservedOsMemory) / (ThreadStackSize) = Number of threads Example: For Java 1.5 I get the following results assuming that the OS reserves about 120MB: 1.5GB allocated to JVM: (2GB-1.5Gb-120MB)/(1MB) = ~380 threads 1.0GB allocated to JVM: (2GB-1.0Gb-120MB)/(1MB) = ~880 threads I love this application server http://www.reviewservers.com/index.php?blog/show/7 Regards, Andrew Hole wrote: Hi!

RE: Tomcat benchmark
From: Andrew Hole [mailto:[EMAIL PROTECTED] Is there any benchmark test available that allow me to determine the number of concurrent requests that Tomcat supports for a particular type of hardware? You already have it: your own Tomcat, your own app, your own mix of requests, and your own hardware (and your own database server and data if you're using them)! Apps and request mixes are so variable that there can be no standard benchmark; instead, you'll have to test your own app using an appropriate stress-testing tool such as JMeter to determine your limits. Sorry not to be able to point you at a standard, but for a typical webapp Tomcat is only a few percent of the load. Any benchmark that omits 90%-95% of the variable isn't useful, in my opinion. - Peter - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Tomcat benchmark
Hello Andrew, if you are looking for comprehensive HW review for particular hardware good luck. The following will get you started and a PDF by Peter Lin using JMeter is the closest I have seen.

Re: Tomcat benchmark
I'm still using tomcat 5 :-) (and Weblogic 8.1), maybe someone interested enough can apply the same test against newer products.
