performance problems

2005-02-24 02:28

I wrote a simple application that generates a pdf file using jasperreport. Datasource is a simple xml-file.

 

When i run this application with SUN sdk 1.4.2 on windows it takes about 2 seconds to generate the pdf file. When i run this application with IBM sdk 1.4.2 on a aix 5.2 System it takes 30 seconds to generate the pdf file.

 

compileReport: windows 821 ms, aix 15260 ms

fillReport: windows 481 ms, aix 13481 ms

exportReportToPdfFile: windows 400 ms, aix 4562 ms

 

Has someone any idea? Unfortunately I have to use aix.

Is it possible to speed up jasperreports on aix / ibm sdk?

 

Best regards.

Today I tested it with the newest JasperReport 1.1.1.

There is still the same performance on aix.

 

Any ideas?

Best regards.

Hi,

 

How much memory do you allow your JVM to use?

If there is not enough memory, the JVM will spend

too much time garbage-collecting things.

 

Try increase the memory with the -Xmx command line

option.

 

I hope this helps.

Teodor
