memcache is much faster than the disk cache.  memcache will not get any
better if no one ever uses it so the openafs developers can get some
bug reports.  i think memcache has improved quite a bit (but it could
be better, i need to submit some patches) over the last couple years.

i use '-memcache -chunksize 15 -dcache 1024'.  if your system is memory
starved this might be an issue.
