: Some users have reported that aggressive CPU power-saving modes (like AMD Cool'n'Quiet) can cause TSC drift that makes these modes "unsuitable". Setting the host to a High Performance power plan may help.

For Windows, check w32tm /query /status and look for large clock skew.
The host CPU may not guarantee a synchronized TSC across all cores (e.g., older AMD CPUs or some Intel models without constant_tsc and nonstop_tsc flags). : Some users have reported that aggressive CPU
Error eliminated. Replication stable. No performance loss.
