[OpenAFS] Extremely poor write performance.

[Rubino Geiß]

I was able to compile arla perf (using --disable-nnpfs), but now I got:

./afsfsperf -host i44pc1.info.uni-karlsruhe.de -volume 536872041 -authlevel
1
afs low-level fileserver performance tester

afsfsperf: RXAFS_MakeDir returned 13

afsfsperf: kocell.c:914: cell_getthiscell: Assertion `thiscell != ((void
*)0)' failed.
Aborted

I guess this is due to authentification problems, but i do have an OpenAFS
admin token, do i need more? arla tokens? dont know...
