Mars Rover Web Site Slows Down, Reports Keynote QUOTE
Dear Industry Influencer: Below is a quote from Keynote’s
senior Internet analyst about the performance of the
two NASA sites we are measuring during the Mars Rover
mission. I have also included a graph which demonstrates
the spike in performance referred to in Mr. Patel’s
quote. The orange line in the graphic is http://www.nasa.gov/home/index.html and the blue line is http://marsrovers.jpl.nasa.gov/home/index.html.
There is background below the quote to give you some
context and some information on Keynote’s measurement
infrastructure and performance indices. We are available
for interviews as well.
QUOTE
“The sites for the Mars Rover images are beginning
to show their limitations. Starting at 9 am Pacific
on
Tuesday, the Home Page download times for both http://www.nasa.gov/home/index.html and http://marsrovers.jpl.nasa.gov/home/index.html nearly
doubled. Download time went from 1.8 - 2.2 seconds
up to as high 4.0 seconds. Those who were fortunate
enough to get through encountered messages indicating
some of the "high demand" content was not
available because of the traffic to the site. The performance
of the sites began returning to faster performance
at about 2 pm Pacific.”
“While the images of the Mars surface are colorful
and rich in detail, not all curiosity seekers are able
to view them due to the high demand. The images that
are posted are large size files (in the MB range) and
can unnecessarily clog up servers' time, not allowing
other users to connect while servicing such large amount
of content.”
