Beware, it's a 3x performance degradation on specific operations (file creation/deletion), the degradation is non existent for other type of benchmarks (at least regarding bonnie++, build.sh or sysbench).
Are you in a position to check where it's coming from?
Not ATM. My spare time is limited right now and I'd prefer to focus on my Xen work first.
