We have a project which have 15 differents components. In the administration tab of this project we keep all the versions of each components. This means we have a lot of versions (~150 versions) for this project (many versions of each components) . When we try to manage those versions (add, delete, release or reorder them) it takes too much time. It can take more than 3 minutes for the request to complete when creating a new version.

I don't know what is causing those delay but it seems to be the only place where Jira is so slow, the other pages are responding relativly quickly and the server doesn't seems to be overcharged since the load average stay low.
