Hi,
What about turning off accessability? Thanks From: shutian liao [mailto:[email protected]] Sent: 13 March 2018 05:42 To: [email protected] Subject: Performance issue on generating PDF file by Apache FOP Hi all, It takes long time to generate PDF file from xslt file to pdf. Following is the time spent(run by junit test on mac) on generating different size, it's almost linear growth with the label count, attach the generated pdf(100 labels) for example. Label Count Time spent(ms) PDF pages Memory Used 100 4306 4 21MB 1000 13247 34 48MB 2000 19334 67 59MB 3000 27473 100 75MB 4000 32489 134 83MB 5000 36252 167 149MB 10000 56195 334 222MB I've tried the following ways to improve the performance, but looks like it doesn't work. 1) Using ByteArrayOutputStream 2) Set strict validation false 3) Cache font file 4) Simplify the xsl template table hierarchy 5) Set JVM -Xms4096m -Xmx4096m I also tried to remove the barcode from label, it can help me save 60% time. And if I remove the label title, it can save another 20% time. So looks like it's related with how much content we want to print. Is it a common problem that ApacheFOP need so long time to generate PDF? Is there any way that can help to improve performance? Any one have experience or suggestion on this?
