Setting IPYKERNEL_BENCHMARK_STARTUP_SHUTDOWN stops the event loop right after it starts, so total process wall-clock time measures kernel startup without needing an actual client to send a shutdown request. This can be used in conjunction with -X importtime and profile viewer like tuna to work on speeding up importing and starting a kernel

I'm fine not merging this, just a suggestion if anyone want to have it later, I can keep it as a local patch. |
