Does your RPi freeze?

in general caching NFS could have some benefits (depending on network infrastructure, server setup etc). but won't bring you any benefit for our usage case.

imagine the situation as follows - normally XBMC fetches directly from NFS, one big file. it loads a portion of the file into memory, decode, display and this repeats.

if you add local cache, XBMC will not use it. as XBMC by default accesses NFS directly. so you can mount NFS locally and reindex you library / XBMC to use "local folder". and now to the process - XBMC tries to fetch a portion of file -> local NFS cache will report not available -> nfs subsystem fetches from NFS -> this needs to be stored locally and then redelivered from local cache to XBMC.

this will only bring OVERHEAD and will not make any profit (on the contrary). because XBMC will not report demand for piece of the file in advance so you won't have any pre-buffers on disk available. never ever.

so don't bother with that.

you are right that with XBian report about streaming problems are very very rare. most of the time they indicate different problem.
what I would do in your case is FOR TESTING PERIOD switching to LAN. that way you can track down if the issue is outside your RPI or inside it and whether it is related to WIFI only or not.

check this out and report back. according to your feedback we can discuss what's next.
