Situation summary for the many-large-files scenario. Something like:

svn checkout svn://URL/ProjX/branches/profile1 ~/test
cd ~/test
svn switch ^/branches/profile2

the branch switch will work nicely with a many-large-files data-set,
only transferring the files necessary to complete the new profile. But
the storage requirements for the working copy (~/test) is twice (2x) the
size of the checked-out data-set.

Alternatively, using the export method:

svn export svn://URL/ProjX/branches/profile1 ~/test

will transfer all of the files of profile1 and the storage requirements
for the working copy is only (1x) the size of the data-set. But
switching between branches is not available in the export method.

To switch branches (using the export method):

svn export svn://URL/ProjX/branches/profile1 ~/test
(transfers all files in profile1)

rm -rf ~/test
svn export svn://URL/ProjX/branches/profile2 ~/test
(transfers all files in profile2)

So basically, the checkout method will require twice (2x) the data-set
size of storage space for a working copy but there would be
significantly less network load during many of the branch switches. The
export method pretty much has the opposite storage/network trade-off.
