    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 : 

      1. Create a bucket with 50M Docs on 100 Collections at ~20% Resident Ratio (KV)
      2. Create 1000 Indexes using PLASMA 
      3. 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.
