Webserver related bottle necks can be found by adding webserver monitors from the controller and analyzing the webserver graphs. Here you can monitor hits/sec, throughput, http response time/sec, pages downloaded per sec, etc… You can also find out if the load generators in the web servers are distributing the load(requests) equally to the application servers? Some times more requests will be send to one application server and the 2nd application server(if you system has) will be sent only few requests etc.. this may lead to long response times.
