Q. Is it possible to allocate more than six threads to the server? I have 8 processor cores available on the Flows server.

A. You can do this by editing the /ns2flows/netsaw.conf file. Simply replace the existing value for "querythreads" with '8'. The maximum number that you can allocate is 20 threads.

querythreads 8

The ns2flows daemon/service must be restarted whenever changes are made the the netsaw.conf file.

Note, however, that only if you do 8 requests at once will it become useful -- that is, having 8 clients connected and querying at once. In short, the number of threads is the number of concurrent requests that IMFlows will service at once without queueing them. So only if you are doing 8 requests for graphs at the same time does it become useful.
