Gitk uses a Tcl associative array for that, which should be very fast.

Could you try this: go to the Edit->Preferences window and turn off "Display nearby tags". Then with your ~2000 refs in place, see how long gitk takes to start up and to display a diff.

If doing that makes it fast, then I suspect that my topology caching patch will also help. That's waiting on an answer from Junio or Linus to my question about making git rev-list ignore negated non-existent refs.

Also, if it's possible to give me a copy of your repo, that would help.
