I summarized these topics and more as a plenary conference talk, including my own predictions (as a senior performance engineer) for the future of computing performance, with a focus on back-end servers. This was a chance to talk about other things I've been working on, such as the present and future of hardware performance.

This included SysAdmin magazine, which contained articles from various experts including Amy Rich, and a couple of advertisements: One was to submit your own articles to the magazine for publication (by writing to the editor, Rikki Endsley) and another was to attend USENIX conferences in the US and learn directly from the experts!

CLI tools The Cassandra systems were EC2 virtual machine (Xen) instances. As a Xen guest, this profile was gathered using perf(1) and the kernel's software cpu-clock soft interrupts, not the hardware NMI. Note that Ubuntu also has a frame to show entry into vDSO (virtual dynamic shared object). But I'm not completely sure.

Earlier this month I spent a week at the OpenStack conference. But once you realize that there are, in fact, several OpenStack conferences happening at the same time and place, it makes more sense. Hardware Optimizers” want to get the maximum utilization out of hardware.
