The rtt is the round-trip time. The mss is the TCP maximum segment
size. The mss of 512 seems very low. If you are familiar with TCP
it is worthwhile to find out whether there is anything on your
network causing it to be that low.

We would not be taken seriously if we were to compile results from
Facebook as it could be argued that the results were faked. Although
the results on this mailing list would be verifiable they cannot be
used as statistically significant results.

Given the absence of any data, it would be useful to compile the
above information and compare the results between ourselves to find
out, for example, whether FTTH is better than FTTH or whether the
latency you are getting is relatively high compared to someone with a
similar internet connection.

A few weeks ago, I replicated the test performed by Facebook to
understand how it works. There is actually a methodology for the test.
