Performance issue in generating PDFs for Custom Fonts in UNIX env.
Hi,
We are using FOP 0.20.5 for PDF conversion. We registered "Courier New"
custom font by following the steps given at
http://xmlgraphics.apache.org/fop/0.20.5/fonts.html#custom
We generated appropriate font metrics file(cour.xml) for cour.ttf file
using TTFReader on different operating systems(Windows and UNIX) based
on their usage.
The performance of generating PDF in Windows env is excellent, but in
UNIX environment it is very bad. For 27 pages document in windows it is
taking 500 ms(approx), where as in UNIX( Solaris) 43587ms (approx).
This is a major hit for us in using FOP. We need a solution ASAP.
Have you ever faced such problem with FOP? Your suggestions will be
greatly appreciated.
Here is the log taken from UNIX environment.

Did you give the JVM for the entreprise environment enough memory to
work with? Such a slowdown is likely produced by the garbage collector
of Java or by the operating system constantly swapping memory in and out.

This is strange indeed, what JVM do you use on Linux? Does the Linux
environment have an X windows server? Does your document have any SVG?
FOP 0.20.5 is no longer actively maintained so you're not likely to get
much of a response I think. My recommendation would be to try FOP
0.91beta and see if the problem persists.
