It is not expected to increase write performance, but it should help
you do something else during that time, or also give more responsiveness
to Ctrl-C. It is possible that you have fast and slow RAM, or that your
video card uses shared memory which slows down some parts of memory
which are not used anymore with those parameters.

I did test some SATA drives, am getting these value for 2.6.20-rc5:-

[sukhoi@Typhoon ~]$ time dd if=/dev/zero of=/tmp/1GB bs=1M count=1024
1024+0 records in
1024+0 records out
1073741824 bytes (1.1 GB) copied, 21.0962 seconds, 50.9 MB/s

What can you suggest here w.r.t my RAM & disk?

Willy

Thanks,
