Thanks for the reply.
The script is a bash script, just to mention.
Meanwhile I`ve figured it out that the sluggish post-receive execution
was due to a (mis)-configuration in the samba share where the remote
repository is hosted. These are:
oplocks = No
level2 oplocks = No
Removing these from the share`s section in the smb.conf solved the
issue, and the push process is taking up around 4 seconds, which I
think is reliable.
Now, do I have to worry about allowing oplocks on the remote
repository from the git point of view? Thinking about concurrent push
operations from different developers?
