hi
There is a HTTP Cache Manager in JMeter but Ive never tried it.

the first thing is , is this your problem though ?
Enable View results tree and see the requests and check what is taking time
in jmeter / what response times you are getting v/s what you see on the
browser (say using firefox and Tamper data/yslow etc)
Also monitor your CPU and memory to see whether 25 is still too much load
per client (how much memory is given to Jmeter as Xmx?)
 (in my case I get 20 threads for 2.4Ghz 2GB - 512MB Xmx , but then I have
vista)
regards
deepak
