this morning ... silly as it sounds ... i went to the following site
http://msn.zdnet.com/partners/msn/bandwidth/speedtest500.htm
which tests your internet throughput speed (nice site!)
and with both ie and netscape open ...
toggled back and forth between the two ... took 10 readings each (by
hitting refresh or reload) ... and here are the data
data are in k bytes/sec ... a reading of 150 is 1.5 Mbps ... or a T1 line speed

notice there is no overlap between the two sets of speeds ... for my sample
... ie was always faster ... than the fastest netscape
i am sure there are many reasons for this ... but, i just pass this along
as a simple "experiment" where two treatments are imposed ...
i would be interested in whether some of you would also do this ... and
report your results
