Re: Progressively longer to initialize Python

I was wondering if anyone else noticed this or has a reasonable explanation for the lag.
Did not have this problem today. Do you have gyros, camera, navx (though, we have a NavX and it works great).

Also, kinda related, but halfway through the competition the first deploy stopped working. We had to cancel the first deploy while it was looking for the RIO and restart deploy to get it to work (sometimes multiple times). It wasn't connection or anything because I made sure the drive station showed Robot code led green before deploying but it was no help..
I think it's mdns related. I had issues with this yesterday on my mac, and basically each time that pyfrc executes a command (I think there's... 4 of them?), it redoes the mdns lookup, so each command is slloooooooow. I ended up just telling it to ssh to the self-assigned IP that the roborio gives itself, and then it was back to normal speed.
