for last couple of weeks (at least) gu.wikisource has become very slow in typing. The issue is specifically on IE9 and IE6, but on firefox, speed is normal. on ws, typing input is very slow everywhere, e.g. search input, page text box, edit summary, etc.
Tried disabling JS in IE9 and that brought back the speed to normal. <Dereckson> & <MatmaRex> tried some bits as well...
