If you've installed the XWiki standalone distribution just be aware that it's not tuned to be production-ready.

As an indicator having a wiki with 9 subwikis (default XE pages) takes around 110MB in memory and you'd need to have more than 512MB or you'd quickly get Out of Memory errors when performing some memory-intensive operations (exports, etc). 8 8 {{/warning}} 9 9 10 10 = Other optional ideas = ... ... @@ -12,9 +12,10 @@ 12 12 * You can use a remote HSQLDB database instead of embedding it.
