[jCharts-users] Re: Performance

Speaking as the author of the message about performance details what
those results meant was don't run a heavily used web app on a PIII with
500Mb of memory and Oracle and iPlanet LDAP running at the same time ...

The production figures (dual Xeon, 4Gb) showed 7 charts a second being
generated. Our extranet web app (not heavily used in terms of hits per
second) has pages that display 30 pie charts at a time. You can beat the
draw speed with a scrollbar but they fill in pretty quickly.

The other thing the performance figures show is that jCharts is one of
the faster Java charting engines (versus jFreeCharts and a commercial
package)

If you want you can check on my web site:
=20
http://www.monentrainement.com, enter the demo by clicking on the "ici"
orange link.
Then select "Demonstration" link, then clic on the "Statistiques"
button, and then
the "Graphic" link.

You will then see many graphs, dynamically generated on the screen.
=20
My opinion is that it is quite fast regarding the volume of data.

Interesting.  So based on that, it may not be the best choice for a
heavily used web app, say if you had several charts on each page, then
the page would take fairly long (in web terms) to load since it takes
over a second at best to create a chart?  Would be nice to allow the
actual chart drawing to be done on the client somehow, guess that might
have to be flash.  Or can SVG do that?

Ok, good to know.  I'll do what the last email said about doing a mockup 
and see how it feels and let y'all know how it goes.
