Seem to run fine so far with rw,noatime,nodiratime,acl,user_xattr,data=ordered,alloc=skip_busy:dirid_groups,packing_groups
Has anyone done any throughput/benchmarks for the various new patches/code?
The block allocator improvements is our attempt to reduce fragmentation. The patch defaults to the regular 2.6.5 block allocator, but has options documented at the top of the patch that allow grouping of blocks by packing locality or object id. It also has an option to inherit lightly used packing localities across multiple subdirs, which keeps things closer together in the tree if you have a bunch of subdirs without much in them.
Any of these new features documented anywhere? ;)
