Well, I don't think so.
1. The benchmark tool was taken from this site:
http://www.caucho.com/articles/jsp_benchmark.xtp it's written in C and
doesn't seem to understand caching.
2. Nothing changed after I added following lines to my servlet
response.setHeader("Cache-Control","no-cache"); //HTTP 1.1
response.setHeader("Pragma","no-cache"); //HTTP 1.0
response.setDateHeader ("Expires", 0); //prevents caching at the proxy
server
Any more ideas?

Perhaps because, in the version without valve, you benchmarking tool use
the expected behaviour of browsers when they have an active cache:
request 'if-modified-since', to which tomcat will respond a 'not modified'.
