>The team are continuing to look into these Lua issues - I'll make sure to pass on these comments, to help us try and get things back to normal.

It is not just an issue with lua, some of those pages are massive, and take considerable time (even with an increase 50MB -> 250MB ):


 * KanColle Kai/Quest

Even if it was just using plain html with no lua processing they would still be cause performance issues. A performance test on the quest page had these   results(http://www.webpagetest.org/result/160722_J8_S04/): 5 MBs, and 5 close to 2 minutes to download the whole page on a fast connection. Of course some of this is due to  uncompressed images and a lot of JS (wikia server issues).
