What benchmark made you conclude that HFS+ is faster than NTFS when using big block sizes ?
None, NTFS is a crap filesystem. I was just pointing out the comparison there is wasteful vs sluggish.
Does anybody still use reiserfs and what makes it "enterprise grade" ?
It's the fastest filesystem I've tested vs ext(s), xfs, and a few others. I had to do a lot of throughput testing on different filesystems so I wrote a battery of tests that helped me figure it out years ago.
Windozes server 2012 uses some of the principles from reiserfs, I don't know if that counts and I can't speak to who users reiserfs commercially but I use it whenever I need something fast and reliable.
The guy may be a killer but he knows how to write a filesystem and I doubt the US military has given up on their investment in it.
Mac OS X still depends on old mac system 6/7 filesystem functionality like resource forks, these are not that easy to "retrofit" in ufs/zfs.
Interesting - I didn't know that - but still sucks for mac users.
A lot of the IO schedulers are implemented mainly to have some IO fairness because mechanical hard drives are very easy to saturate.
and also to make it look like all the processes running behave smoothly - if you have a dedicated application though your still s.o.o.l on a mac
These aren't that useful anymore when you can push 500.000 IOPS to a set of SSD's. And don't diss the FreeBSD storage subsystem: ufs allows for consistent backups without having to use volume management and creating a snapshot beforehand (LVM2+ext4).
Now way would I dis FreeBSD - I'm might be a linux guy but I still think BSD is a solid offering - and good on them for having apple use their work - they deserve more credit. Though ext4 suffers its own issues if you need to have big directory structures.
I'll stick with my guns here though, any limitations on linux disk performance is a function of how well the controller drivers implement the hardware functionality. Configurable I/O, CPU scheduling, software and hardware raid coupled with filesystem choice make Linux reign supreme in terms of achievable I/O performance.
