[jira] [Created] (INFRA-4736) slow authentication to
git-wip-us.apache.org
Brandon Williams created INFRA-4736:
---------------------------------------
Summary: slow authentication to git-wip-us.apache.org
Key: INFRA-4736
URL: https://issues.apache.org/jira/browse/INFRA-4736
Project: Infrastructure
Issue Type: Bug
Security Level: public (Regular issues)
Components: Git
Reporter: Brandon Williams
Priority: Minor
Pulling from git-wip-us.apache.org is very speedy -- if you aren't authenticating. However, as a committer you're always authenticating, and this is painfully slow.
Without authentication:
{noformat}
time git pull
Already up-to-date.
real 0m0.430s
{noformat}
With authentication:
{noformat}
time git pull
Already up-to-date.
real 0m17.767s
{noformat}

[jira] [Closed] (INFRA-4736) slow authentication to
git-wip-us.apache.org

Joe Schaefer closed INFRA-4736.
-------------------------------
Resolution: Won't Fix
This is a client-side bug in git. I've dtraced the performance
of my git client with both https and http running, and there
is a 50ms select call that's times out in each read loop on
the socket. The problem is that there are something like
350 select calls (which means read-loops due to smaller reads)
in the https case, but only 10 in the http case. This is a known
issue (google git https slow) and may be fixed in the latest version of git.

Unfortunately, no:
time git pull
Current branch trunk is up to date.
real 0m17.796s
user 0m0.212s
sys 0m0.084s
I repeated it again to make sure it was cached with no change.

This is a damn shame, but your analysis looks correct. Thanks for the effort in any case, Joe!

-------------------------------------
I believe this was caused by SSLSessionCache not being properly configured in the server.
It's since been fixed - notice any differences?

Joe Schaefer commented on INFRA-4736:
-------------------------------------
Ok. In any case this is an SSL perf issue not an auth issue- your
password isn't checked unless you are pushing something.
I will have another look at the SSL config on the server to
see if I can change something on our end to improve the situation.
