Ludovic, thanks for the handy tips, but ... I need some more :) I have installed the Admin Tool and it mentioned that indexes were not created. So before creating indexes I have decided to upgrade table engine from MyIsam to InnoDB as Sergiu has suggested in this post http://xwiki.475771.n2.nabble.com/Upgrade-to-3-2-minor-issues-td6883965.html After the change the overall time to load main XWiki page as administrator has gone from 5 to 25 seconds. My wiki currently is 1100 documents in count and 400M in size. Quick questions: * is caching enabled by default? * is caching limiting done simply by document count or by allocated memory (as most recent EHCache allows)? After the upgrade, I receive following error on "XWiki Database Indexes Check" page * Failed to check indexes for wiki xwiki: Table 'xwiki.xwikiattrecyclebin' doesn't exist I think this is related to fact that my database name is "xwiki_utf8_innodb" and not "xwiki", because I receive similar results on "MySQL Encoding Check" page * Failed to check xwikidoc encoding for wiki xwiki: Unknown database 'xwiki' * Failed to check xwikidoc encoding or collation for wiki xwiki: Table 'xwiki.xwikidoc' doesn't exist but I don't know where to change that parameter to proper value - velocity scripts are overcrowded with 'xwiki' strings. -- View this message in context: http://xwiki.475771.n2.nabble.com/Activity-performance-is-slow-tp6961805p696...
