[egit-dev] Performance of Synchronize - unusable for CDT

[James Blackburn <jamesblackburn@xxxxxxxxx>]

Hi egitters!

The CDT community is very diverse and many of us are keen to switch to
git as the distributed model will really help those who build products
outside of eclipse.org.

Unfortunately we're struggling with synchronize to compare changes
between branches within the IDE.  This is a key part of the workflow
when preparing patches for bugzilla, reviewing and integrating
changes.

On my machine time to synchronize two branches is 33 mins.  Time to
perform the diff in cgit is 2s:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=323839

Can anyone provide any detail on what the cause of the slowness might
be, and how hard it would be to fix?  This might spur someone on to
dig into the code while waiting for the synchronize to happen :)

Cheers,
James
