Possible delete performance degradation

Current graph of delete times is here: <span class="error">&#91;2&#93;</span>.</p> <p><span class="error">&#91;2&#93;</span> <a href="https://jenkins.opendaylight.org/releng/view/controller/job/controller-csit-3node-benchmark-all-neon/plot/getPlot?index=6&amp;width=900&amp;height=900" class="external-link" target="_blank" rel="nofollow noopener">https://jenkins.opendaylight.org/releng/view/controller/job/controller-csit-3node-benchmark-all-neon/plot/getPlot?index=6&amp;width=900&amp;height=900</a></p> <p>I think the fluctuations are probably due to the amount of load in the infra/env at that time - a volatile env is not ideal for benchmarking/performance testing. </p> <p>I remember that in early Nitrogen the volatility was low and it jumped sharply. I do not recall any infra change at that time.</p> <p>We should be able to eliminate the environment effect by re-testing Carbon, if the current CSIT code can run that.</p> <p>Cannot reproduce now, let's reopen if occurs again.</p> Development External issue ID 9236 External issue URL Issue Type Rank 0|i02snz:
