ACK.
it's surely in our mind to provide as much information as we can. I'm also 
planning on a second dedicated machine, which has a Pentium 4 with 
HT-technology to provide the SMP-part of the merge-times. In the future, 
if all is running and the response of the users is good enough, we hope 
that we can also provide the merge-times for other architectures than 
x86.

By the way, as long as we dont have a second machine with smp-support, it 
should be possibly to get reasonably accurate results if we multiply the 
number of cpus and then divide through a factor like 1.2. You can test 
it, it should be reasonably accurate.

But as I said, we are planning on a second machine with smp and also on 
merge-time information for other architectures.

(please overlook my horrible grammars)

Yours sincerely,
