NCache 4.3 - Online Documentation


StressTestTool.exe allows you to quickly simulate heavy transactional load on a given cache. And, this helps you to see how NCache actually performs under stress in your own environment.
Please watch NCache performance counters in NCache Manager "statistics" or in regular PerfMon.
A test case represents a user session or multiple get and update operations on the same cache key. Use test case to simulate an ASP.NET or JSP sessions. When all test-case-iterations are used, a user session becomes idle and left to expire.
Each test-case-iteration consists of one or more gets and updates (ASP.NET session simulation would use 1 get and 1 update). And test-case-iteration-delay represents a delay between each iteration and can be used to simulate ASP.NET session behavior where a user clicks on a URL after 15-30 seconds delay.
For .Net setup: stresstesttool cache-id [option[...]]
For Java setup: java -cp "stresstesttool.jar:$CLASSPATH" mycache
