GC Performance OS and Hardware Comparison Differences: Windows Intel vs. Ubuntu Intel and Windows Intel vs. Ubuntu ARM #85483

Open mrsharm opened 1 year ago

mrsharm commented 1 year ago

Summary

This issue tracks the work associated with identifying and solving the discrepancy between Windows Intel vs. Ubuntu Intel and Windows Intel vs. Ubuntu ARM based on the GCPerfSim Scenarios.

The general themes in terms of the results are:

  1. Windows Intel based traces exhibited a higher execution time than their Ubuntu based counterparts.
  2. % Time Spent in GC for Linux based runs is, in general, much higher than the Windows based counterparts.
  3. Results on the ASPNet Machines are far less volatile (minus a few outliers sprinkled here and there) than those on our GC machines implying a need to establish some protocols such as logging other users off before running any of the tests.
