Subject: Number of worker processes on hyperthreaded processor
Date: Mon, 19 Nov 2012 11:17:41 +0100	[thread overview]
Message-ID: <39816208-25A9-4F8E-A0E0-51621F9C4D5A@airbladesoftware.com> (raw)

Good morning,

The tuning page says worker_processes should be at least the number of CPU cores on a dedicated server.  In the case of hyper-threading, should this be the number of cores or the number of threads?

For example the Intel Core i7-2600 Quadcore[1] has 4 cores and 8 threads.  Would I start my worker_processes at 4 or 8?

Finally, would the same apply to Nginx worker processes?

Many thanks,

Andrew Stewart
