That said, is there any plan to change how this functions in the future
to solve these problems? I.e. have it not use so much diskspace and
thus use less bandwith. Am I misunderstanding in assuming that after
say 1000 commits go into the tree it could end up several megs or gigs

Burst is good. There's another window in the SCSI layer that limits to
bursts of 128 sector runs (this seems to be the behavior
on 3Ware). I've never changed this, but increasing the max number of
SCSI requests at this layer may help. The
bursty behavior is good, BTW.

I was curious if your patch would change the write rate because I see
only ~550MB/s (continuous) which is about a factor two away from the
capabilities of the disks.

much between 2.6.10-bk6 and -bk7...)

For 3Ware, you need to chage the queue depths, and you will see
dramatically improved performance. 3Ware can take requests
a lot faster than Linux pushes them out. Try changing this instead, you
won't be going to sleep all the time waiting on the read/write
request queues to get "unstarved".

We have a rx4640 with 3x 3Ware 9500 SATA controllers and 24x WD740GD HDD

With kernel 2.6.11 the read performance on the md is reduced by a factor
