[xwiki-users] Performance of "Edit Objects" menu call slowed down after creating 1000 users

Hi, i've created 1000 users via Groovy script. Each user document (profile) has a TacClass, a XWikiUsers and two XWikiRights objects. If i call the object editor at user profile page to make some changes to XWikiUsers object it takes long before the data appears. Other object edits slowed down as well. Is there a known reason? Is there a known possibility to accelerate access to objects belonging to the current document (creation of some index in database, ...)? Thanks, Rudolf Tronicek "50 erste Dates" mit Adam Sandler u.
