Good Day,We are running SQL Server 2008R2 Ent 64 bit with 32 CPUs and 256 gig of memory. We ran diagnostic scripts to identify any bottlenecks and found that ony 4 processors are relatively busy processing only between 4 and 7 processes each.When I ran sp_who3 I noticed that the lastwaittype on some of the processes is SOS_SCHEDULER_YIELD , meaning the cpus are under pressure . Now I am baffled ,because the users also are not complaining . Any ideas ? |

This is not necessarily an indication of CPU pressure.What are you seeing in perfmon for % Processor time? Have a look at this blog and the Waits and Queues White Paper |
