Re: Subversion 1.0.4 very slow with large files

Hi,

i can only second that (ok i'm still using subversion 1.02 but ...)

The time seems to grow exponentially with the filesize. We have
a vendor branch with some libraries exceeding 40MB. The checkout
of such a library can take more than one hour :((

I just tried to check out the lib directory using 'file:///' and it
worked
pretty fast (a few minutes).

Since upgrading to 1.1.0 doesn't seem to do the trick (see mail below),
does anybody have a hint on what to do?

Regards,
                Max
