Benchmark fsync

Download a binary from github or build from source (see later).

fsyncbench [flags]

Flags

-n=100: Iterations to test - default 100
-dir=/tmp: Target directory - default os.TmpDir()

It will produce output like this

$ fsyncbench 
2013/07/02 16:03:30 That took 988.255164ms for 100 fsyncs
2013/07/02 16:03:30 That took 9.882551ms per fsync

You'll need go installed, then

go get github.com/ncw/fsyncbench

and this will build the binary in $GOPATH/bin. You can then modify the source and submit patches.
