Hi, I have a plan to play with TCG performance benchmarking. And then try to implement some optimizations. So maybe there would be some suggestions on how to perform such benchmarking? What tests seems to be appropriate for this task? I think the benchmarking should reflect real TCG use cases. So what the most typical use cases for TCG are there? Seems that system and user modes may be different from this point. Appreciate any help. Thanks, Sergey.
