It works very poorly during my daily train commute where GSM internet connection quality varies widely from second to second, minute to minute.

I wondered what was going on when I switched to several tabs and found only a few posts had loaded.

Normally, I read one thread while loading others in tabs; generally they load at 40 per page eventually. It becomes a form of buffering.

With Infinite scroll this does not occur. Basically it is inefficient.

I have had to turn it off.
