On Campus Command Line: iperf -c 10.0.13.68 -w 2m

Off Campus Command Line: iperf -c 132.170.3.31

results should look like this:

------------------------------------------------------------
Client connecting to 10.0.13.68, TCP port 5001
TCP window size: 8.00 KByte (default)
------------------------------------------------------------
[1924] local (your IP) port 1500 connected with 10.0.13.68 port 5001
[ ID] Interval Transfer Bandwidth
[1924] 0.0-10.0 sec 111 MBytes 92.9 Mbits/sec

Make firefox faster

Type in firefox address bar

about:config

Then set the following preferences to the specifed values

network.http.pipelining = true
network.http.pipelining.maxrequests = 30
network.http.max-persistent-connections-per-server = 50

Explanation of Preferences

network.http.pipelining
This preference has an effect only if you are not using a proxy. Pipelining reduces network load and can reduce page loading times over high-latency connections (not supported in all servers).

network.http.pipelining.maxrequests
This preference specifies the maximum number of requests to pipeline at once when pipelining is enabled.

network.http.max-persistent-connections-per-server
Corresponding to the maximum number of HTTP keep-alive connections the application can have open at once to a single server.
