Hi Paul - Well, you don't state whether you're broadband or not, but
assuming you are, this is the best site I'm aware of for speed testing
because it offers multiple locations so that you can see the effect of
different geo distances. I've found it to be quite consistent and
repeatable.

Some cautions -
1. If you are using ad blocking in Zone Alarm, turn it off for the duration
of the test(s). Other ad blockers may also possible interfere.
2. There are a large number of variables involved in the determination of
your actual speed. You need to make multiple runs of these tests from all
of the test locations at that site, at various times of day, on various days
of the week to get a fair assessment of the speed range you are actually
experiencing.
3. DNS lookups from DNS servers on the net can in some cases consume
considerable time, particularly where bad hops are involved. You may want
to immediately repeat a test so that you can see the effect of using the
cached results the second time. You'll find it illuminating, I suspect. If
you're looking at performance improvement, look into using a local DNS
server on your on machine. I highly recommend Treewalk, here:
http://ntcanuck.com/ Easy install and works just as advertised right out of
the box. ntcanuck also has a news server which has groups which may be of
interest - news.ntcanuck.com
4. TCP/IP parameters are some of the most significant variables over which
you have any control which affect your network speed. I strongly recommend
using the appropriate parameter sets from Cablenut, here:
http://www.cablenut.com/ Be sure that you also download and use the Update
Package. READ CAREFULLY the Help/Readme and spend some time in the Cablenut
forums to get up to speed - this is by nature a complicated issue. I would
recommend that you start with the parameter set from the Update package
which most closely approximates the nominal up/down speeds offered by your
ISP. You can then experiment from there, if you're so inclined, but that
set will likely offer significant improvement over the OS defaults without
further tweaking.
