I think I finally found the main issue (system load was just a side-effect):
https://code.google.com/p/gerrit/issues/detail?id=2406 -- I changed my Putty
settings, case closed.

Well, I *did* monitor the system load during my git fetch calls -- otherwise
I would not have bothered the mailing list: There was no Jenkins job
running, CPU was nearly idle, Gerrit's web interface was as responsive as
one could wish for, and so on ...

Furthermore I tried calls from outside the university's network, from
within, and even on saros-build itself. The ssh connections were always
slow, http(s) connections were not fast, but ok. All I asked for was "does
anyone else suffer" -- obviously nobody did, so I got this problem all for
myself. End of story.

Best Regards,
Franz

As our whole build server is nothing more than just a VM (running in a very
very BIG cluster) I would stop asking those questions until the problem
stays permanent.
