The following Red Hat Compatible Kernel (RHCK) Hyper-V updates have been made:
Improved Hyper-V storage driver performance
The
storvscHyper-V driver update provides a moderate performance improvement of I/O operations when using the driver for certain workloads.Hyper-V clocksource support for Time Stamp Counter (TSC) page
TSC page is now used as the Hyper-V clock source. TSC page computes the per-guest reference counter value more efficiently than the model-specific register (MSR) that was used previously. As a result, kernel operations that involve reading time stamps are faster.
