>> What are the performance difference if i use MMAP or not ? mmap is a kernel syscall that simply map a file into a single address space to simplify programming (seek, r/w) into file. Generally mmap I/O is faster than block reads. Mmap on NFS can give some problem, i don't know about mmap behavior on clustered fs.
