Linux "SpadFS is a new filesystem that I design and develop as my PhD thesis. It is an attempt to bring features of advanced filesystems (crash recovery, fast directories) and good performance without increasing code complexity too much. Uses crash counts instead of journaling (because journaling is too complex and bug-prone) and uses hash instead of btrees for directory organization."

Thanks for the fine.

The numbers look good but I don't understand what all the numbers mean.

What's the difference between lin/spad, spad/spad and spad/ext2 on the graphs?

Perhaps we'll see. This filesystem has been out in the wild for less than a month it seems. Hopefully as it gets more exposure folks who already have benchmarking systems all set up will put up their workload numbers. Also we'll see what sort of refinements get added and what they do to the speed.

I believe one is the "source" filesystem and the other is the "destination" filesystem.

SPAD was defined as an OS kernel that is also in expirimental stage. Apparently the author is an OS writer, too. So basically he's comparing SPAD and Linux OS kernels with the different file systems running beneath them.
