Wait Rate

Metric Description

Average Wait time (in milliseconds) per synchronization context switch. Low metric value may signal an increased contention between threads and inefficient use of system API.

Possible Issues

The average Wait time is too low. This could be caused by small timeouts, high contention between threads, or excessive calls to system synchronization functions. Explore the call stack, the timeline, and the source code to identify what is causing low wait time per synchronization context switch.

Product and Performance Information

1

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.
