Hello Raz,

Yes, it provides very good bandwidth for my I/O intensive parallel programs.

You should keep in mind that PVFS is not a general purpose filesystem;
it is intended to be used in situations were multiple processes
read/write large amounts of data in parallel.  Also, PVFS performance
is poor if you access the filesystem in small chunks (since there is
no caching mechanism).  Therefore, your program should read/write in
large chunks for good performance (I use a size of 2 to 4 MB).

Hope this help out,
