Hi Peter, Once again thx very much for your reply... As you've given that the mem settings are too high for my client who would be havin a max of 1GB....So in such cases using concurrent collector would lead to memory leaks....I really hope if i change my mem settings it would affect the performance again slowing it (for single user at a time)drastically apart from concurrent hits slowness..... So, I juz wanna ask u or any of the guys watchin this post here, to give me ur valuable suggestions/links on how to collect gc details on a web application without doin much with the app....mean to say the configurations/steps i need to do for getting the GC details output for my web app at run time....Really I dont have any exposure till now about how to get GC details...plz do guide me in this....
