Any thoughts about performance?

You have now met my friend named "JVM startup" :-)

Yes, you could probably get that down to less than 30 seconds by only
starting a single JVM in a batch job and communicating with it from RPG
using data queues. Though I shouldn't speculate too much because I haven't
been on a machine with only 1GB of memory in a loooong time. This is the
same approach I use for RPGChartEngine ( - free and open source).

Performance may be a moot point, however. PDF reports are a requirement!

What is your timeline for needing it? Maybe we could trade some Java open
source work for some RPGUI open source work :-)

One thing that motivated me to download pd4ml was a performance benchmark,
published on their web site, which indicated much higher throughput than
that of my testing with Aaron Bartell's HTML2PDF4i utility. My original
thought was that a performance advantage alone might justify the additional
cost of a pd4ml license. However, both utilities appear to offer identical
performance in generating an identical 150 page PDF document on my server.

That may not be saying much. It takes 2 minutes to generate that PDF on my
server. To be honest, that kind of performance is a bit repulsive to me.
I've done a number of performance tests, and I think these Java jars may be
a case where my 1 Gig of RAM, is insufficient.
