Sql Server Low Cpu Usage


Can you take a short rest while unconscious? Also, breaking the load into smaller transactions might help (avoiding log growth and other issues). When CPU utilization and context switches both exceed their thresholds regularly, this indicates a CPU bottleneck. of rows. Source

Hyper-threading essentially leases time on the physical processors so that each processor ends up more fully utilized. Often what you see, though, is that SQL Server's CPU usage is very low, but the system's paging activity is very high.
