The problem with cfs is that you still suffer the RPC to check for validity. With 100ms of RTT, count 5 and you have a second. Also, for synthesized files, the cache does not save you from doing a walk, open, read.
That sayd, I don't think a change in 9p is needed. Translating to another protocol for low links suffices. On 6/24/07, Lyndon Nerenberg <[EMAIL PROTECTED]> wrote:
Before we think about turning 9P into NFSv4, it would be useful to examine the current use of cfs, and collect some stats on how effective it is.
