global_data is the one and only special page PhpWiki keeps around to 
store/restore its system-wide, not page-specific state.
It should not be deleted, but it causes no critical errors if you 
already did.
It could be any other pagename also. (See lib/WikiDB.php:538)
PhpWiki uses the special metatag "__global" in global_data for its 
special data.
Every WikiDB::get() - WikiDB::set() call uses this area.
Currently we use it for non-critical values,
the DB _timestamp, plus some global stats.

See http://mywiki/global_data?action=DebugInfo
or http://mywiki/global_data?action=EditMetaData

I doubt that the pages you deleted which are just id's of links affect 
system performance. But closing stale httpd and mysql processes may 
drastically increase performance.
