Filling report very slow using custom JRDataSource in 5.6.1 compared to 3.7.1

[stegea]

Hi guys,

I'm experiencing the following issue genereting a report with JasperReport 5.6.1 compared to the 3.7.1 version. The filling process is very slow!! I'm using a custom datasource (A Java object implementing the JRRewindableDataSource). From log4j output i can see a great bunch of time is lost in loading subreport (they are in a local dir) and in fetching some bean regarding font. If I run the same report in 3.7.1 everything is fine and fast. The same if i use a db connection in both versions... but i need to run it with a JRRewindableDataSource.

Any clue?

Any advice wil be appreciated!!

Thanks in advance

I am going to assume that both are not on the same system.
You might want to check many fonts are installed on each?

I have run into issues on old DTP systems where literally thousands of fonts were installed
resulting in very slow print times. Removing redundant fonts helped speed things up.

Otherwise do you have a bit more information about how things are setup?
