There have been some performance issues since the last release of XWiki that was installed on this server. The database was heavily loaded by the wiki engine because of a change in the code.
This issue has been fixed and some additional changes are making the caches much more efficient.
So the performance of XWiki.com should be much better than it was in the past days but also better than it was before the latest release of the code.
A new release for the engine will be release next week with these changes for people having a local install of XWiki (Note that on a local wiki, the performance problems are not as a big issue than on XWiki.com which handles many wikis).
Thank you for your patience.
