<DIV>Of course, the trick in all this is to make the tests repeatable so that
comparisons are meaningful. I agree with Tony that accessing select maps,
wiki pages, and perhaps videos are good candidate load tests and I would add
some collaborative tests that exercise ejabberd.</DIV>

such testing is warranted and will certainly be helpful. <BR><BR>My intuition is
that videos should be downloaded to the Journal and viewed with the Jukebox
activity. <BR>Aside from the obvious advantage in that the child can take the
laptop home and view the video at his or her leisure, a download supports
sharing of the bandwidth. That is the approach I have taken with
<BR>BERNIE.<BR><BR>Perhaps Adam can give us an idea of the situation at the
deployments in Haiti. Saint Jacob's represents a reasonable example of the
deployments I am familiar with: three classrooms, 30-40 XOs per classroom, a
total of 100 XOs connected to a single school server, one router per classroom,
dhcp provided by the server (all laptops on the same LAN).
<BR><BR>Representative tasks:<BR><BR>A classroom of students performing a map
lesson with open street maps - locating their school by moving the map center
and zooming in until Kigali is at the center with maximum zoom.<BR><BR>A class
doing a research project on different types of reptiles using wikipedia for
schools. Each student is to write a report of 50-100 words with an image of a
reptile they select. Assume they search for reptiles. Go to the article. Select
a reptile type, e.g. lizard and then download an image from the
article.<BR><BR>A class doing a Khan Academy lesson, e.g. multiplying 2 digits
by 2 digits, on with some watching the video and then doing the associated
exercise, others doing the exercise. <BR><BR>Tony<BR><BR>

moz-do-not-send="true">http://schoolserver.org</A> onto a system like
Nepal's $275 MSI DC111 or comparable/faster. Cheaper is great if
performant!<BR>
<LI>Copy IIAB (all ~700GB if possible) to that school server's internal HDD
using "rsync -a" (too many issues with dd).<BR>
<LI>Curt is helping me distribute a brand-new release of IIAB to testers in
coming weeks -- allowing diverse speed tests of Wikipedia's experimental new
full-text-search and Open Street Map?<BR>
<LI>Later/Bonus: are there cases where IIAB on an external USB3 drive is
almost as fast as an internal HDD? 2GB RAM as good as 4GB RAM?<BR>
<LI>When the going gets tough evaluating 3rd world deployments' imminent
HW/SW choices, compare notes on irc chat channel #schoolserver (<A

<LI>Scream for real (with joy ;) during our weekly Thursday calls no matter
how ugly things get! </LI></OL>
<P>Thanks for bright ideas, any/all! Thousands stand to benefit, and
rather quickly. So far, possible early areas of investigation are
summarized here:</P>
