Chris,
Sorry I should have posted the data first. I probably missed the most important
part of a load test. I will do it shortly.
And I am not using Jmeter now,I am using an http client for load test. I am
testing it on Solaris x86 server 64bit JVM. And i have collected the samples
for Tomcat

Chris,
With c=1 it is 70k req/sec and with c=2 it is 35k in both i.e the total req/sec
cannot be scaled beyond 70k. With Tomcat 6 it is 60k in both clients i.e total
of 120k.
I do not expect more than 75k req/sec being served by Tomcat 7,but its the
benchmark set by Tomcat 6 which I can't over

I would have to upgrade to minor version of Tomcat 6 otherwise.

While it's nice to reduce resource utilization as much as

Yes. With same JVM on both Solaris and Linux i.e Java 1.6.39. It is 64 bit
version.

I'd upgrade to the latest 7.0.39 but otherwise, definitely time for a
profiler.
If you want raw performance on kept-alive connections then BI
Another important factor is the CPU utilization. Earlier for same trans/sec it
was 40% now its close to 80%.
And yes,the OS,JVM and memory setting are unchanged.
Thanks.

I am comparing tomcat 6.0.18 with tomcat 7.0.30.
Would adding NIO or APR connector help? Currently I am using default(BIO)
connector.
Thanks.
