Hi, We have tomcat instances that run ~20 webapps without a problem. Beyond that, we haven't tried, but then again that's why we have tools like JMeter, no? ;) In large part this will depend on the soundness of the application. Especially if it's 100 of the same app, because then each memory

God save our apps from any memory leaks. Of course we will test them for this issue. And perform stress testing 20 sounds fair enought. Frankly I don't expect too much traffic per e-shop. Niki Shapira, Yoav wrote: Hi, We have tomcat instances that run ~20 webapps without a problem. Beyond that,
