I run it on a VPS. Works great across oceans. Biggest gripe is that it doesn't load local content first. It checks online and then pulls from those thumbnails. So if you have a weak or slow connection, then you'll get a spinning wheel of death or assets that don't load properly.
PWM dimming turns pixels on and off to make them darker. So for 50% of the brightness, it's off 50% of the time. Higher end panels flicker much faster which helps mitigate perceived flicker. I think 500hz and above is preferred.
For DC dimming is just using voltage to control the darkness with no flickering involved.
I have a 7840U with a 55HWr battery. I can squeeze out 7 hours. If I'm power using then 5-6 is typical. With the 63WHr battery, you'll get about 15% more time with it.
Client side or server side?
