Right, I've restored the file of 1915 packed tags (but not the 35 loose
tags). Using DNT for "display nearby tags"

DNT on: consistently 11s to window appear, 20s to normal cursor
DNT off: consistently 11s to window appear but normal cursor immediately

Regarding getting the diffs, I think that was "user misunderstanding" and
I'm doubting if I definitely did click on the blue circles yesterday. Clicking
on the any part yellow tag marker displays the SHA of the tag object
(which I'd confused with the start of an unfinished commit diff);
for some reason I'd thought it would give the diff-with-parent. Clicking on
either the blue circle or "commit headline text" does bring up the diff
instantly even with the packed refs file. Sorry for the confusion.

I'll privately mail Paul about getting it; if anyone else wants a copy
of the repository
in order look at startup performance issues mail me. (The most embarassing
thing in there is just some astonishingly crap code, but I'd prefer not to
blanket publish it.)
