Industry db benchmark result on recent 2.6 kernels

We will be taking db benchmark measurements more frequently from now on with
latest kernel from kernel.org (and make these measurements on a fixed interval).
By doing this, I hope to achieve two things: one is to track base kernel
performance on a regular base; secondly, which is more important in my opinion,
is to create a better communication flow to the kernel developers and to keep
all interested party well informed on the kernel performance for this enterprise
workload.

I'd guess that doing it on kernel.org is too late, sometimes. How high
is the overhead of doing a test? Would you be able to test each -mm
release? It's somewhat easier to toss something out of -mm for
re-review than it is out of Linus's tree.

The overhead is fairly high to run the benchmark. It's not a one minute run.
(more or less like a 5 hour exercise. Benchmark run time along is 3+ hours).
-mm has so many stuff, I'm not sure we would have the bandwidth to do a search
on which patch trigger N% regression, etc. Let me try the base kernel first
and if resources are available, I can attempt to do it on -mm tree.
