[fuse-devel] FUSE vs kernel filesystem

[Niraj k. <ni...@gm...>]

Hi,

I have been trying to understand/learn FUSE recently and
may consider writting a new filesystem using FUSE. However,
before starting that, I wanted to evaluate FUSE on the following
points:

1) Performance - How much impact is there on the performance if a filesystem
   is implemented using FUSE compared to a filesystem written in
kernel ? I can understand
   that FUSE implementation will be slow, but I want to know if there is
   any ballpark figures available...

   As an example, say if I want to write an NFS client using FUSE, how
   will it fare compared to existing kernel based client ?

2) Limitations - Is there any other limitation in implementing any feature
as compared to kernel based filesystem?
