This test checks internet performance and latency. Overall an interrupt driven benchmark with variable number of running processes.
Topdown profile includes higher amounts of frontend stalls and not as many backend stalls.
AMD metrics show on average barely 1/3 of a core running, reinforcing the interrupt driven nature. This is floating point code with a moderate L2 access. Higher amounts of opcache and icache misses corresponds to the interrupt driven nature.
