Description Paige Rubendall 2022-03-01 19:19:44 UTC

Description of problem:
On the new ASH cloud cluster type the etcd-perf test is not within threshold of 10000000 ns. On 2 sepearate test the thresholds were about 18743296 ns, much higher than expected and higher than the same test on aws, alibaba and ibm cloud

Version-Release number of selected component (if applicable): 4.10.0-0.nightly-2022-02-26-230022


How reproducible: 100%


Steps to Reproduce:
1. Install cluster ASH cluster at version 4.10 (I used versioned-installer-ash_wwt template from flexy)
2. git clone https://github.com/cloud-bulldozer/e2e-benchmarking.git
3. cd e2e-benchmarking/workloads/etcd-perf
4. ./run_etcd_tests_fromgit.sh


Actual results:
Max 99th fsync latency observed: 18743296 ns


Expected results:
Max 99th fsync latency observed: at or under 10000000 ns


Additional info:
Must gather and inspect of namespaces will be in private comment
