How often do you do such operations ?
Those times doesn't sound like something excluding documentation will fix, nor
do they look extremely slow for a large codebase ?

So the problem is windows ?

I do them to get fresh updates, to commit to both brunches, and sometimes to
find the version in which a bug is introduced. Last month, because of
xulrunner and docs in trunk, my updates took ~8 hours.

By deleting all docs from trunk and moving xulrunner to a different
directory, the time of 21485 to 21862 updating has reduced to 0h29m (better
than 2x improvement).

I mean that long updates take approximately the same time on both systems.
Thus no, windows is not the problem.

version in which a bug is introduced. Last month, because of xulrunner and docs in trunk,

Fresh updates - sure, but that does not take long if you do it often.
Commit to both branches - don't you have two copies or do you really do svn switch
between them ?
xulrunner updates happens very rare so I'll assume it only caused problems because we
did a big update ?
Docs - well, then just exclude it.
The solution for this is to get our Tycho build running and have a snapshot (p2)
repository setup so you only have to get
the module(s) you are interested in changing as source and get rest as binary
dependencies.

By deleting all docs from trunk and moving xulrunner to a different directory, the time
of 21485 to 21862 updating has reduced to 0h29m (better than 2x improvement).
because changes happend in that area, right - if those changes happened in VPE or JSF
would you also want to remove that ? :)
But yeah, if splitting the build up doesn't help in this area moving docs might be the
best option, but not right now.

Big commits/movings always lead to long updates.
Commit to both branches - don't you have two copies or do you really do svn
switch between them ?
I have them now, but remembering old days it was faster to do svn switches,
than to maintain a copy. And it does not solve the problem with rolling back
to previous revisions.
xulrunner updates happens very rare so I'll assume it only caused problems
because we did a big update ?
Right.
Docs - well, then just exclude it.
The solution for this is to get our Tycho build running and have a snapshot
(p2) repository setup so you only have to get

The idea is to exclude all _unnecessary_ folders from local copy :) It is
simple and it works.
But yeah, if splitting the build up doesn't help in this area moving docs
might be the best option, but not right now.

that all depends on the amount of deltas which will always vary over time.

And docs are unnecessary ? They need to be built and maintained too...not just by doc team
;)
