25 seconds is quite not
Chris,
This is one possible implementation of the clustered writeback idea.
It runs OK on ext3 (compiling, syncing, etc.).
The patch is based on 2.6.23-rc3-mm1 and the writeback patches here:

By default, with many dirty inodes, it works as follows:

Because it does the work in small batches of 10 inodes, when the
system has =10 dirty inodes, its behavior will reduce to:
- do a full sweep *at once* on every 25s
Which means the disk will flicker once every 25s, not bad :)
