| ### Micro-benchmarks |
| |
| ## Environment |
| |
| The benchmarks recorded below are obtained by running zircon-benchmarks in a |
| release build of fuchsia via ssh. When the benchmarks are recorded the Fuchsia |
| user shell (GPU-accelerated) is running but no user has yet logged in. |
| |
| These are the running processes at the time of the benchmark: |
| |

| The typical thread load of the system before running the benchmarks (via k threadload): |
| |
| ``` |
| cpu load sched (cs ylds pmpts) pf sysc ints (hw tmr tmr_cb) ipi (rs gen) |
| 0 0.01% 32 0 0 2 51 0 3 3 9 0 |

| 3 0.15% 196 0 0 20 492 0 60 60 32 28 |
| ``` |
| |
| It is believed that the running processes has a very minor impact on benchmark results. |
