gclient sync very very slow

[Fady Samuel]

Hi all,

gclient has been very slow for me lately (taking 2 or 3 minutes before
it start doing anything). Anyone else experience this? What can I do
troubleshoot this? Thanks,

Fady

I haven't seen this yet.

A good first step is probably to find out what exactly in gclient is
slow. You can add progress logging to the gclient scripts or use
system tools such as strace on linux or dtruss on OS X to get a first
idea.

gclient autoupdates itself on every startup – maybe that's the slow
step. You can follow the steps at
http://www.chromium.org/developers/how-tos/depottools#TOC-Disable-auto-update
to disable the autoupdate and see if it helps (if you do this, be sure
to have some cronjob that does this update, else it's pretty likely
you will run into problems caused by an outdated gclient script later
;-) ).

Hey Fady,

gclient might be taking longer on some repository, but it can
checkout others in parallel using the -jN switch. Try "gclient sync
-j8" for example, if you haven't tried that yet.

Hope this helps :-)

Any reason it doesn't do this by default?

Some race conditions I've never taken the time to fix. Oh well.
