#122 slow svn co http://svn.fedoraproject.org/svn/hosted/...
Closed: Fixed None Opened 16 years ago by apevec.

We noticed slow checkouts via anonymous http://svn.fedoraproject.org/ while the same co via svn+ssh is acceptably fast, for example:

time svn co svn+ssh://svn.fedoraproject.org/svn/hosted/aplaws/users/
real ~ 20s

time svn co http://svn.fedoraproject.org/svn/hosted/aplaws/users/
real ~ 6min

I guess this also affects other hosted projects based on Subversion.


In addition to that, anonymous checkout is not possible from some boxes (IP address available on request). The svn+ssh checkout from the same box works nice, wget http://svn.fedoraproject.org/svn/hosted/aplaws/users/ works, but the:
{{{
svn co http://svn.fedoraproject.org/svn/hosted/aplaws/users/
}}}
simply hangs. Here's the output of netstat -t:

{{{
Active Internet connections (w/o servers)
Proto Recv-Q Send-Q Local Address Foreign Address State
tcp 0 372 local.address:39472 git.fedora.redhat.com:http ESTABLISHED
}}}

The box is running RHEL4U5.

I am having the same problem here. I am using subeclipse and I cannot even browse the Repository as it hangs until it fails

svn: PROPFIND request failed on '/svn/hosted/aplaws'
svn: Connection reset

I'm slowly working on this issue with GIT, they don't seem to think there is a problem. For now use https instead of http.

apevec, can you email me what location you are attempting to connect from? mmcgrath redhat.com.

Hosts I tried were in RHT MUC office.
But now http://www.ohloh.net/projects/5256/enlistments/new doesn't seem to accept HTTP SVN URL at all: after submitting, hangs at Checking server connection...

just to be clear, does the svn+ssh still work from there?

Same problem here.

Using the machine in my home office (German Provider Arcor, 82.82.0.0/15):
For a checkout of trunk via svn+ssh needs 4 min 38 sec.
For a checkout of trunk via http: after 90 min about 20% of the modules were downloaded.
A checkout via https didn't work at all (405 Method Not Allowed)

Using my machine at university (high speed German Research Network, 134.102.0.0/16)
a checkout using http doesn't work at all. After trying for 6 min the fedoraproject host cancelled the connection.

does the svn+ssh still work from there?

from RHT MUC svn+ssh works fine,
and ohloh.net can't use svn+ssh

HTTP seems to be fixed in the meantime,
reported test case svn checkout is now ~23s via

NB: as a workaround project Aplaws has setup a svn mirror at http://svn.aplaws.org/svn/aplaws/
This is also used to generate commit alerts (ticket 123)

Can anyone else that was having this problem please re-test. We've had another request come in from RHIS following up. I'm ont sure if they made any changes or not.

That was from a RHT internal machine (MUC office)
From outside it either slow (test case is ~7.5min) or doesn't work at all

Same goes here. I have tried on our corporate network and it took over 20mins to check out the trunk.

This should now be fixed. Long story short we had to:

net.ipv4.tcp_window_scaling = 0

on the svn box. We will likely have to leave this set until the cisco firewall we are behind is upgraded. In the meantime though, this slowness should be gone.
