Hi! Here's a better set of numbers, using the finobt-enabled userspace.
Some cosmetic errors in my chart-generating Perl script were also fixed.
Revised legend:
v4: v4 XFS
v4dirent: v4 with Mark's dirent patches
v4d512bi: same as above, with 512-byte inodes
v5: v5/CRC XFS, no finobt except for "finobt" patch case
Again, a kernel git dir was built, then turned into a source tar.gz
file for these tests.
Files involved in find/sha256/cp/stat tests:
$TEST_DIR/a/linux/ (kernel + xfs-oss/master, built)
$TEST_DIR/b/linux/ (same)
REAL
command patch v4 v4dirent v4d512bi v5
