I have an application that creates some 228 thousand files,
spread over about 4000 directories. Total is not more than
1.3Gb.  (I'm not sure, and I don't care if it's 10% or 90% of
that number)

Anyway, I've loaded all of the 1.3Gb into the cache (the machine
has 8Gb of RAM), so that only writes need to take place.

After a while the machine goes into a routine of writing
about 500 to 1000kbytes per second.

Sync seems to take a long time:

The as-iosched has a sync bug, and if you are using that, then try deadline 
instead.


Thanks!
