Increase Thread Allocation in Large Deployments

The System Requirements in the Release Notes advise you to provision a server with multiple CPUs in larger-size deployments. We recommend changing the thread_concurrency parameter to account for the number of CPUs on the server.

Follow these steps:

1. Log in to the server where you have installed CA Performance Center.
2. Edit the following file:

   /etc/my.cnf
   

3. Search for the 'thread_concurrency' parameter.
4. Change the number of threads to equal two times the total number of CPUs on the server.
5. Save the file.
6. Stop and restart the mysql daemon by entering the following commands:

   service mysql stop
   

   service mysql start
