TESTING
- extents testing
- Discussed methods for testing extents on highly fragmented
filesystems.
- Jose will look into possible tests, including perhaps using the
'aged' option in FFSB
- Ted suggested creating a mountoption that creates a bad block
allocator which it jumps to a new block group every 8 blocks. This
would force a very large number of extents, and may be a good test for
extents.
there is AGGRESSIVE_TEST define which limits number of entries in index/leaf.
- Large file deletion
- Valerie had recently tested large file deletion on ext3/4, but did
not see the expected performance gain with ext4 due to compact metadata
when using extents.
any details?
thanks, Alex
