CPU usage profile during Blueos initialization #1808

This isn't an issue, it is just to show our CPU usage profile during initialization.

From what I could detect during a previous personal investigation, is that starting the http servers uses a huge amount of cpu. We should consider improving it somehow, maybe cashing something on python compiler side ? Don't know.

I believe that is also the issue responsable for the resets that we see, the system takes so long to start that bootstrap thinks that the system broke.

I did a quick test with nuitka, I was able to get it working and with others services, but it appears to compile only the python code that it can see, without doing some smart stuff that pypy could.

Talking about pypy, they do not provide binaries for arm32, only arm64. It may worth to add it in our base image and checkout.
