Inactive Sync Wait Count

Metric Description

Inactive Sync Wait Count is the number of context switches a thread experiences when it is excluded from execution by the OS scheduler due to synchronization. Excessive number of thread context switches may negatively impact application performance. Apply optimization techniques to reduce synchronization contention and eliminate the problem.

Product and Performance Information


Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
