Since instances of both CentOS and Ubuntu were running in parallel, I could collect flame graphs at the same time (same time-of-day traffic mix) and compare them side by side. As a Xen guest, this profile was gathered using perf(1) and the kernel's software cpu-clock soft interrupts, not the hardware NMI. But I'm not completely sure.

Vertical scaling is also often discussed, which involves increasing the resources of a single server, which can have limitations in hardware capabilities and become costly as demands grow. Depending on the database size and on disk speed, a backup/restore process might take hours or even days! An example is running MongoDB on Mesos.

Reducing CPU Utilization to now only consume 15% of initially provisioned hardware. The second example was around web-server threads, which turned out that the team ran with default settings for Apache (200 worker threads) which was too low for the traffic the government agencies are receiving during business hours.
