Basically, this issue:
https://bugzilla.kernel.org/show_bug.cgi?id=198197
..is affecting a cloud provider on a 4.15 kernel.
Customer testing with a kernel that is patched with the fix (upstream: 512ac999d2755d2b7109e996a76b6fb8b888631d ) confirms that it resolves the issue.

[Impact]
* Aggressive throttling by CFS causes severe performance degradation in some cases.
[Test Case]
* This reproducer clearly shows the problem before the fix and shows no problem after the fix:
https://gist.github.com/bobrik/2030ff040fad360327a5fab7a09c4ff1
[Regression Potential]
* It touches core scheduler code so regression could be bad - but risk is low as the patch is accepted in mainline and tested separately by myself, the cloud provider, and at least 2 others. |
