ext2 is incredibly better. Machine is very responsive. 

OK.  Please, always monitor and send /proc/meminfo.  I assume that the
dirty-memory clamping is working OK with ext2 and that perhaps it'll work
OK with ext3/data=writeback.

Nope. Dirty is still very high..

That's a relief in a way.  Can you please try decreasing the number of
filesystems now?

Here is the data with 5 ext2 filesystems. I also collected /proc/meminfo
every 5 seconds. As you can see, we seem to dirty 6GB of data in 20
seconds of starting the test. I am not sure if its bad, since we have
lots of free memory..

Thanks,
