You assume that the file operation performance of Windows on NTFS and Linux
on NTFS is the same - which I am sure it is not. First of all the NTFS
driver on Linux is FUSE-based so it runs in userspace and therefor slower
than kernel based drivers such as ext4. Also ext4 is one of the most used
file system on Linux so I expect its code to be much more optimized.
Another interesting data point might be: what does the client-side

I tried that, it bring down the checkout times (better result of two runs):
* Linux ext4: 1m 15s
* Linux NTFS: 3m 2s
* Windows NTW: 6m 52s
So there is no noteworthy change on Linux but Windows performance improved
by 25% (9m 19s down to 6m 52s). It is still slow and further improvements
would be welcome.
Also: it would be good to know the exact versions of sqlite and other
