Except "mem usage" column, Windoze task manager features "VM size" column. > Also, I do experience OutOfMemporyExceptions ... In the set components I use there is no memory leaks. You should provide more information on what do you use, what your sitemap looks like, what is the size of XML docs. I assume that you have OutOfMemoryErrors when testing with just one concurrent user.
