Juergen,
To make you feel better: I serve Subversion on a super fast Linux Enterprise
server with 4 Xeon processors, tons of disk space, and tons of RAM. All the
users' desktop clients are Pentium4 @3-4GHZ with WinXP + 512MB to 1GB of
RAM. And a complete fresh check out still takes 20-25 minutes for a 250MB
project! Sometimes my patience just runs out. Not to mention it's
extremely CPU intensive and takes my PC hostage. I literally cannot do
anything until SVN is done checking out. NOW, consider yourself lucky :)

I've had some experience with large check-out/in. The problem isn't the size
itself, but the number of files.It looks like most file systems has a
noticeable overhead for each file it has to create. I've had some problems
related to this when checking out a working copy to a nfs mount. NFS
performs really poor when trying to perform operations on many files.
But to answer your question, I don't think 10-12 minutes are that much
considering the number of files. Remember that all later operations will
only be performed on a small amount of data. If you keep your working copy
on a network drive, you can probably improve performance by moving it to
your local drive, but that might lead to some backup issues..
