Hello everyone, My HP Proliant Microserver, which I want to use as a NAS, is using an AMD Turion II Neo N40L processor. The plain disks give me about 100 MB/s using filebench with the fivestreamwrite/multistreamwrite workloads (as software RAID-1 under Linux and zpool mirror under FreeBSD). In Linux, using LUKS with cipher aes-xts-plain64 on a software RAID-1 I get the same ~100 MB/s for the same benchmarks. In FreeBSD, using a mirror zfs pool with underlying GELI with AES-XTS I get only ~50 MB/s. As the encryption algorithms should be the same, I'm wondering why FreeBSD is that slow for nearly exactly the same use case. Any ideas how I could tweak my settings in FreeBSD?
