The newer versions already have decent blocksizes. Configuring the mountpoints with the async option should again speed up writes a bit. > 2) > Is there a package (preferably within Scientific Linux Packages - if not > easily compilable) to do benchmarks on a mounted NFS filesystem? > Possibly print out latency and IOPs?
