Subversion Windows Performance compared to Linux

Hi,

this topic was raised several times in the past - the answers range from
"will be better/solved in the next version 1.7" or "it is due to ntfs vs
ext3/4" or it's the AV, network setup or the Windows file indexing
service. After disabling all those and running a test checkout on Linux
and Windows on the same machine I still get a result of Linux being 7.3x
times faster. Any ideas why?

Versions:
 * 1.8.8 on Linux
 * 1.8.6.254 command line from tortoise
 * 1.7.16 svnserve linux

Note: Upgrading the server might be an option but I guess that is not the
root cause of the problem here?

The repository:
 * Checkout size: 8.9 GB (without .svn folder 4.9 GB)
 * 410 Folders
 * 23,706 files

Commands used to test:
 * Linux: $ time svn co svn://10.0.0.1/test > /dev/null
 * Windows: PS Measure-Command { svn co svn://10.0.0.1/test > $null }

Results (tests run twice, better result taken):
  * Linux on ext4 (journaling enabled): 1m 16s
  * Linux on NTFS*: 3m 29s
  * Windows 7 on NTFS*: 9m 19s

[*] Same partition

Client Machine
--------------

 * Intel(R) Xeon(R) CPU E3-1230 V2 @ 3.30GHz
 * checkout to HDD not SSD
 * 1 GBit LAN to server
 * Linux, Fedora 20 64 bit
 * Windows 7, 64 bit
  * AV deactivated
  * IPv6 deactivated
  * Windows file indexing service deactivated
  * Windows auto updates deactivated

Server Setup
----------------

 $ svnserve -d --memory-cache-size 2048 -r /srv/svn_repos/
--cache-txdeltas yes --cache-fulltexts yes -c 0

Thanks for any pointers,
Florian
