[OpenAFS] Debugging a network performance problem that affects AFS

We're having intermittent network performance problems, and the primary 
manifestation to us as users looks like "an OpenAFS slowdown."  I'm 
wondering if it's possible to collect access time statistics out of an 
OpenAFS Linux client.  A little time with google and I see the 
"-enable_peer_stats" and "-enable_process_stats" options when starting 
the client daemon, and this very well may furnish the information that I 
need.  A subsequent search gets me to the "rxdebug" document, though 
that document appears to be server-centric as opposed to querying the 
client.  Nor does it tell me what information I can collect or if access 
time is part of that information - only mentioning serveral parameters 
that it does collect.

Can someone toss me a bone here - or a link?
