Magit slowness

[Timothy Licata]

Hello group,

First of all, love Magit, thanks for the development effort.

I recently setup a new Ubuntu machine. Setting up Emacs (25.1.1) included downloading a new version of Magit.

I noticed `M-x magit-status` now takes 7-10 seconds. Any thoughts on how to speed this up? A `git status` in the same repository takes < 1 second. So does `M-x magit-status` in the same repo on an old machine.

Other operations, including staging and unstaging, have also noticeably slowed down.

Current (slow) version: 20170104.1507 (w/ Git 2.10.2).
Previous (fast) version: 20160418.1513 (w/ Git 2.8.1).

Thanks,
Tim

Can you do M-x start-profile RET RET M-x magit-status RET M-x
profile-report RET on both versions and see where the change is?

Thanks for the hint. The profiler didn't appear to blame Magit.

I'm afraid my initial comparisons weren't valid. One ran on a host
machine and the other on a guest. The VM is the likely culprit.
Magit just happened to be the point where I felt the slow down.

Apologies for the noise,

Tim
