Subject: bufferbloat on Nokia N900 (and probably anything with GPRS?)
Date: Thu, 4 Aug 2016 20:52:25 +0200	[thread overview]
Message-ID: <20160804185225.GA12637@amd> (raw)

Hi!

GPRS/UMTS modem on N900 seems to have rather severe bufferbloat
problem -- after area of bad signal is encountered, pings are in 200
_seconds_ range.

I guess it would be good to reduce the queues, and probably drop
packets when signal is too low.

Any ideas how to make GPRS more usable?
