Hi Sebastian,
Can you walk through your setup and testing environment in a bit more
detail? What kind of performance numbers are you getting from the
kernel interface and pvfs2 apps? Does the performance degrade over
time the longer you have the kernel mounted, or does it start off bad?
Thanks,

Hello,
I'm about to test the pvfs2 filesytsem on our setup, which
comprises two i/o servers also configured to be metadata servers
and clients. In addition there are other clients. Clients should
use the kernel interface rather than the libpvfs2 library. However,
the performance of the system using the kernel interface drops to
an unusable speed while it seem to be fine with the libpvfs2 based
tools. What can be the issue here?
Kernel (for all participiating servers and clients) is 2.6.21 on an
amd64 debian system.
Thanks in advance!
Ciao,
Sebastian
