KV 2022-Jan
Description
When checking the daily showfast perf results for "KV : DCP, 250M x 1KB items, DGM", I noticed that recent runs (from the last 2-3 days) are showing a ~3.5x reduction in throughput - see http://showfast.sc.couchbase.com/daily/#/history/KV%7CDCP,%20250M%20x%201KB%20items,%20DGM%7CAvg%20Throughput%20(items/sec) :
Both builds 6.6.5-10072 (highlighted) and 7.1.0-2020 show a drop in throughput; these were both run in the last few days:
- 7.1.0-2020: http://perf.jenkins.couchbase.com/job/triton/43970/ , Started 2 days 16 hr ago, Took 1 hr 20 min on triton-client
- 6.6.5-10072: http://perf.jenkins.couchbase.com/job/triton/43984/, Started 3 days 11 hr ago, Took 1 hr 47 min on triton-client
There hasn't been many changes in KV-Engine on mad-hatter branch (only backports), so this is either an issue with a recent backport or someting environmental.
Starting initial binary chopping on kv-engine builds (are fewer changes on mad-hatter so starting there).
