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."

Disk: WD Caviar 160GB SATA, 20GB test partition at the end

Filesystems are tested on Linux 2.6 and Spad (not yet released kernel with experimental features).

write, rewrite, read 8GiB file, report average data rate and CPU consumption in seconds.

Take file on-src-20060814.tar (OpenSolaris sources), already unpacked, and try:
tar xf; cp -a the whole directory; grep -r on the whole directory ; rm -rf
