upload frontend: limit at 256KB
more ongoing experimentation. 1MB seems to work pretty decently.
I've tried 512KB before, but reverted after seeing very little
effect. I may not have waited long enough to see it, though.
Also, recent data analysis for the backends indicates 256K might
be a much better value here anyways.
