Hmm -- looks like 2.9 defaulted to autoCommit=false, but that can't

It perhaps could in conjunction with file synchronization on commit...

everything on an fsync(single_file))

It is autocommit. Changing it to false for 2.4 brings it down to one minute slower than 2.9.

When its on, wa is 20-30% and the cpu just barley moves. When its off, its a similar profile to 2.9.

Theres a speed trap :)

I'm on ext4.
