NOTE: This suggestion is for JIRA Server. Using JIRA Cloud? See the corresponding suggestion.
When debugging a suspected GreenHopper performance issue in OnDemand, I did some profiling on an instance to get to the root of the problem. It looks as though the Flowdock for JIRA plugin is doing some very expensive PropertySet creation in an IssueEventListener. This might not have been picked up on in regular JIRA usage, as most of the time IssueEvents are fired for only a single issue (create, update, etc). However GreenHopper updates multiple issues at a single time in a loop, and the slowdown caused by this extra code is very noticeable.
OnDemand instances bundle the Flowdock for JIRA plugin by default. Thus this could be a big problem for a lot of customers. Note that I tried to disable the plugin to see if the problem went away, but it still persisted.
