Hi,
thank you for your answer.
I removed the git Debian package and compiled v2.6.2 manually. The
performance is much better now (on the same level als v1.7.12.4).
We opened a Debian bug report, to request a git version >= 2.6 to be
backported to jessie:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=802661
The issue is now solved for us, thanks again for your quick response.
Best regards,
Daniel Steinborn

currently we are experiencing poor write performance when a repository
is pushed to a nfs volume. Interestingly, this seems to be a problem
in newer git versions:
v1.7.12.4: Very good performance
v2.1.4: Bad performance, up to 6 times slower
Are there any changed default settings or new features that can be the
reason for that problem?
Please ask for specific details if they are neccessary.
Between 1.7.12.x series and v2.1.4, there are more than two years'
worth of changes, so it is unreasonable for anybody to expect that
such a question can be answered in a meaningful way.
Have you tried more recent versions yet? 2.1.x series is over a
year old, and I am reasonably sure there have been tons of "earlier
we did X for correctness, which unfortunately made things slower,
and this ensures the same correctness in a different way that is
much more performant" fixes since then.
