You can redirect it like this on Linux: $ fop -q ... 2 /dev/null or like this on Windows: C:\fop -q 2 nul Are you sure that you want to suppress those warnings? Consider a DocBook document that I am working on now. When not suppressing warnings, I get among the output: ... Font ZapfDingbats,normal,700 not found. Substituting with ZapfDingbats,normal ,400. Couldn't find hyphenation pattern for lang=en. ... With -q, the font warning goes away, but the hyphenation warning remains. If I suppress the hyphenation warning, I will not know that there is a problem.

Re: Performance improvement suggestions
Hi,
tables are good for data grids, but you can use alternate solution in
many cases.
Example 1: Border can apply to many FOs, so you don't need to use table here.
Example 2: title starting with graphic symbol:
table solution needs a complete table structure:
fo:table/fo:table-body/fo:table-row, plus 2 table-cell (witch consumes
time and memory)
Alternative: only 2 fo:block-container:
fo:block-container keep-with-next=always space-after=-{$my_inner_height}
!-- graphic block --
/fo:block-container
fo:block-container start-indent={$my_width_allocated_to_graphic_symbol}
fo:block start-indent=0My title/fo:block
/fo:block-container
Note that such solution need to understand how indent inheritance is
done in XSL-FO (see [1]).

2013/1/14 nels nbhc...@gmail.com:
My first FOP project ... I am trying to provide near instantaneous conversion
of XML to PDF for our users and have written a custom XSL-FO. Having read a
number of threads here I have seen the suggestion to replace PNG images with
JPG. I have done this though from my timings I can't say with certainty that
run times have reduced. I have seen other suggestions and seek some more
information as to how to implement them - they are:
load style sheets into memory,
use a server VM and
don't use tables.
The third suggestion I could probably do but would take a fair bit of effort
and I would like to know up front if this would speed things up
significantly. Also how do I draw the table cell borders if I don't
explicitly use tables?
Any assistance appreciated.

Welcome to FOP. Having read a number of threads here I have seen the suggestion to replace PNG images with JPG. I have done this though from my timings I can't say with certainty that run times have reduced. I have seen other suggestions and seek some more information as to how to implement them - they are: load style sheets into memory, I guess you mean keeping in memory a javax.xml.transform.Templates object for each XSLT and I assume that you are embedding FOP in your application (if not, then it will be much faster). Using Templates is a good practice, easy to implement, so do it but don't expect to see big differences. Also note that this step is not really part of FOP. FOP consumes the XSL:FO which is the output of this transformation. use a server VM and Yes, it will definitely help. don't use tables. I am not aware of any significant performance penalty due to the usage of tables. For big tables, there was https://issues.apache.org/jira/browse/FOP-1888 which is fixed in the latest 1.1 release. If you really need tables for your layouts then use them and come back to it, if you later see that this is slow. You will have to write at least how many pages your documents are and what you mean by near instantaneous conversion. Assuming you have images and an output of 2-4 pages, it will be hard to get below 100ms per document, after warming up. Having said that, here is some other points that will help: * Create a single org.apache.fop.apps.FopFactory and reuse it. It should be thread-safe and this is how you will get the best performance after rendering a couple of documents (warm-up) * Make sure the JVM has enough heap (-Xmx). I would not recommend below 512MB. * If you don't need complex script support (e.g. Arabic, Hebrew scripts), then use userAgent.setComplexScriptFeaturesEnabled(false); * This is obvious, but use the latest FOP release. There are some other more advanced tricks one could use. They are harder to implement and don't apply in all cases. For example, about 80% of the time is to convert from XSL:FO to FOP intermediate format and the other 20% is from the intermediate format to the final PDF format. So caching or producing directly the intermediate format is faster. This is of course FOP specific, not well documented and might not be compatible with past future FOP versions.
