[jCharts-users] Re: Performance

[Chris M. <ch...@de...>]

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)
