Hi Keld: Do we have raid5/6 numbers for linux on any multi-core CPU? Most of the benchmarks I have seen on wiki show raid5 perf to be ~150MB/s with single core CPUs. How does that scale with multiple cores? Something like intel's jasper forest??? If available, can u pls point me to numbers with multi-core CPU? Thanks!
