I may have missed them but some things to consider from my point of
view are the following: NTFS always uses ACLs, ext4 surely won't and
ACLs are more processing intensive than old style Posix permissions.
Where did you store your working copy? Vista and Win 7 have changed
the users directory structure by being backwards compatible using
junctions. Depending on your checkout directory, resolving a junction
may impact performance on each and every activity of your file system
regarding the checkout, something which surely won't be the case under
ext4 again because most of the users simply store in /home/xyz without
any links involved. I may be wrong here but does Linux on NTFS still
ignores ACLs as well? It surely did in earlier versions.

How much RAM was provided for both OSes during the checkouts? How much
was used for cache?

Besides all that, a complete Process Monitor log for filesystem
activity on Windows would surely be helpful, but a lot of work to
properly research it of course.

Mit freundlichen Grüßen,
