Re: High CPU Utilization

created by Amol Walanj in Performance Tuning - View the full discussion

My goal is to gain high TPS with avg. response time below 25ms and low CPU Utilization.
My client is a normal HttpClient written in Java.

Using Thread Pool Executor I manged my client side threads.

 

Peter ,

 

I didn't worked with Rajesh. The issue you mentioned also looks similar to mine.

But here you mentioned by increasing the threads the more load on CPU.

what I had found from my testing is there is 1-2 % increase when I increase almost 10 threads from the client.

But the CPU is largely depend on the maxThreads of the http connector configuration in server.xml under deploy/jbossweb.sar directory.

 

I had calculated the time taken to complete 1 Query.

It's in the range of 5-15ms

 

So What I can see that the max CPU is Utilized in Handling connections.

So I want to optimize this connections handling so that to reduce CPU with high TPS.

 

Thanks,

Amol
