[Subclipse-users] svn ant task : Checkout of large project takes enormous time, while export is quite fast

Hi All,

 

I am using svn Ant task to checkout an extremely large project (some 60
mb, 43 000 files).

System Ubuntu Linux, svnkit library used.

 

Export from a repository in LAN takes few minutes.

However, checkout of the same module takes hours (actually, never
finished).

What is funny, checkout using the same Ant script via VPN (WAN), with
some 1mbps speed, takes shorter, some 2h.

 

Something like:

                <svn username="${svn.user}" password="${svn.password}">

                    <checkout
destPath="${tmpdir}/${module.dir.prefix}/${module.name}"
url="${module.url}" />

                </svn>

 

Checking out other module from the same repository (small one, some 200
files) succeeds without problems, so it does not look like a
configuration problem (the only thing that changes is the last element
of URL). Checking out the module from command line takes several
minutes, same with Windows client (TortoiseSVN).

 

Any hints welcomed, I need this badly. I will fall back to using exec
task to call command line svn client, if I cannot solve it soon ... but
still it seems strange.

 

Additionally, I may add that the ant script is part of CI build using
Hudson, but this should not matter (ant is called the normal way).

 

Is it normal that checkout takes so long on Linux, especially comparing
to export ?

 

Regards,

Krzysztof Trojan
