Description
On running a 1000 Index test on Plasma with OSO Enabled , we see that the time for initial build of indexes is more than that with OSO Disabled
The test config is as follows :
- Create a bucket with 50M Docs on 100 Collections at ~20% Resident Ratio (KV)
- Create 1000 Indexes using PLASMA
- Calculate time to build these 1000 Indexes
Results are as follows :
Bucket RR | OSO | Initial Build Time | Job |
---|---|---|---|
~20% | Enabled | 20.3mins | http://perf.jenkins.couchbase.com/job/hemera/744/ |
~20% | Disabled | 10.8mins | http://perf.jenkins.couchbase.com/job/hemera/745/ |
100% | Enabled | 19.9mins | http://perf.jenkins.couchbase.com/job/hemera/747/ |
100% | Disabled | 10.6mins | http://perf.jenkins.couchbase.com/job/hemera/746/ |
All runs are on 7.0.0-4253.
