[jira] [Comment Edited] (SOLR-16530) Performance degradation due to eliminating noggit Writeable
[ https://issues.apache.org/jira/browse/SOLR-16530?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17631070#comment-17631070 ]

Hey [~ichattopadhyaya] would you mind adding a bit more context here for posterity/clarity?
e.g. What are the red and blue lines on the graph you attached a screenshot of? What's the relationship between the "screenshotted" graph and the one at "http://mostly.cool/cluster-test-with-patch.html"? (I'm assuming that the screenshot is just a static capture of the HTML page, that you took because the dates covered by the HTML page will shift as time passes, but an explicit confirmation there would be great.) What is the "patch" referenced in the url "cluster-test-with-patch.html"? What does this perf test do in a sentence or two? etc. Is the Y-axis on this graph in seconds? How significant is this slowdown in amortized terms?
I know some of this context is in Slack, but not everyone has access there.
