What network did that box have?

I'm finding that with OpenAFS, and memcache, read performance is
affected greatly by the -chunksize argument to afsd. Using -chunksize 20 
(1MB chunks) gets me around 50MB/sec, while -chunksize 18 gets
5-7MB/sec. (I believe that's the size of the 'fetchrpc' calls)

Another question with the afs client.. I'd really like to use the kafs
client to mount a root filesystem, then use OpenAFS to mount /afs so
I can have read/write support. I went so far as to patch kafs to mount 
as type 'kafs', but then found that both clients want to listent on port
7000. Can I either

	a) change the port for kafs
	b) get working read-write and auth support for kafs?

I'm guessing a) is much more likely..
