I dont have authority over iGen, but I am pretty sure that with sysbench
we should be able to recreate the test case or even dbt-2
That said the patch should be pretty easy to apply to your own workloads
(where more feedback is more appreciated ).. On x64 16 cores might bring
out the problem faster too since typically they are 2.5X higher clock
frequency.. Try it out.. stock build vs patched builds.
