Improve polling speed and reduce latency #19

Anything less than 6000 doesn't change latency, but it does put a load on the CPU. I don't know how it works. By making the polling rate 144hz in a variable the author was clearly guided by something, but I can't find what. Either I don't understand how the speed is actually adjusted.

In any case, before the minimum from the client was 6000, I accidentally changed it to 4000 for some reason. I have not been able to get a delay of less than 7ms. It feels like it's some kind of limitation of the WiFi adapter.

I've read VitaDev and VitaSDK, but I can't find anything about WiFi settings, or any ways to configure it.

I tested the evening with this, pooling-rate above 8000 was starting to noticeably worsen latency. Anything below 6000 just makes the PS Vita warm the air, without affecting the data rate in any way.

Interesting, I think we can look into this further after we refactor the code
