Yes, we are seeing higher system % on the CPU, not sure how to quantify in terms of % right now - will check into that tomorrow. We were not checking the context switch numbers during our benchmark, will check that tomorrow as well. -----Original Message----- From: pgsql-performance-owner@xxxxxxxxxxxxxx [mailto:pgsql-performance-owner@xxxxxxxxxxxxxx] On Behalf Of Josh Berkus Sent: Thursday, February 14, 2013 6:58 PM To: pgsql-performance@xxxxxxxxxxxxxx Subject: Re: High CPU usage / load average after upgrading to Ubuntu 12.04 On 02/14/2013 12:41 PM, Dan Kogan wrote: > We used scale factor of 3600. > Yeah, maybe other people see similar load average, we were not sure. > However, we saw a clear difference right after the upgrade. > We are trying to determine whether it makes sense for us to go to 11.04 or maybe there is something here we are missing. Well, I'm seeing a higher system % on CPU than I expect (around 15% on each core), and a MUCH higher context-switch than I expect (up to 500K).
