Kata revision history page & 500 Internal Server Error

Discussed in #2921

Hi, I authored a kata a while ago.
Now, nine out of ten tries I cannot access the kata revision history page due to 500 Internal Server Error.
Perhaps I revised it too many times that getting revision history causes timeout?
If so, is it possible to squash some earlier commits?
Thanks!

This should be a separate issue. It seems to have many revisions, and it's slow to compute some of the diffs.
