Should I assume (since this is the OpenAFS list) that these parameter changes
are source code changes?

We're running vanilla AFS 3.5 from Transarc/IBM.  Is it a safe assumption that
I can grab the OpenAFS sources for "vos", make rx parameter changes as above,
compile it and use it in my cell without too much trouble?  I've never worked
with the OpenAFS sources yet.  Is it going to be more trouble than the
performance increase is worth?
