OpenDir performance: Read DirIV once and reuse it for all names Formerly, we called decryptPath for every name. That resulted in a directory walk that reads in all diriv files on the way. Massive improvement for RM and LS (check performance.txt for details) VERSION UNTAR RM LS v0.4 48 5 1.5 v0.5-rc1 56 19 7 v0.5-rc1-1 54 9 4.1 <---- THIS VERSION

All test performed on tmpfs, /tmp/a mounted on /tmp/b.
benchmark.bash: double write length Writing 1000 128KB blocks takes only 1 second and yielded inconsistent results. With 2000, things look saner.

The untar test uses https://cdn.kernel.org/pub/linux/kernel/v3.0/linux-3.0.tar.gz .

The archive is placed on tmpfs as well.
