Speed of annotation is mainly due to getting the file history more then calculating the actual annotation.

I don't know *how* file history is stored in the others scm, perhaps is easier to retrieve, i.e. without a full walk across the revisions...

In case you have qgit (especially the 2.0 version that is much faster in this feature) I would be very interested to have annotation times on this file. Indeed annotation times are shown splitted between file history retrieval, based on something along the lines of "git log -p -- <path>", and actual annotation calculation (fully internal at qgit).

I would be interested in cold start and warm cache start (close the annotation tab and start annotation again).

Thanks (a lot) Marco
