fast internet connection but very slow browser response
My browser connection has become very slow. Pinging will show a very
fast connection, but my browser response is often so slow that a
request times out. Skype will work fine under these conditions, as
well as my torrent agent.
I looked at 'syslog' and the output below seems to me related to the
problem, but I don't have the expertise to have much more than a
suspicion about it. If anyone could help me interpret the stuff
relative to my browser problem, I'd very much appreciate it.
my browser is iceweasel and i'm running Jessie.
