So linux inefficiencies are a big problem here too.

- mschuster91 7y agoOn anything embedded, the performance of Samba is atrocious compared to plain old nfsv3, which in turn is slower than iSCSI but that comes with its own troubles. Personally I prefer NFS at home, but what I really really want is a NAS that doesn't cost four digit sums and can do full-disk encryption on RAID basis without the performance tanking. iSCSI with OS X clients sucks.

- StillBored 7y agoI use LUKS on my work laptop (company policy/etc). Sure the AES-NI bandwidth is a few GB/sec/core. But it definitely slows things like kernel builds down by more than double digit percentages. Turns out latency is still important for storage and making an extra pass over all the data doesn't help.
