My dream is to turn computer performance analysis into a science, one where we can completely understand the performance of everything: of applications, libraries, kernels, hypervisors, firmware, and hardware. I'll also have the opportunity to hire and mentor staff and build a team of the world's best performance and debugging engineers.
