jasper performance issue

2006-01-19 11:37

hello,

 

has JasperFillManager.fillReport() been tested under simultaneous requests?

 

i run fine with 1 thread (grinder load testing, 1 thread == 1 virtual user).

 

with two threads throughput slows considerabley.

 

with three threads the system barely moves, hanging on this call:

 

jasperPrint=JasperFillManager.fillReport(jasperReport, parameters, conn);

 

thanks,

 

tom

fyi - i am running FirstJasper.jrxml to HTML export using JR 1.1.1.

 

i think that the lock up is in net.sf.jasperreports.engine.fill.JRVerticalFiller.fillReportContent()

 

and the looping which calls fillReportContent() on JRVerticalFiller.fillReport()

 

...

while (next())

{

fillReportContent();

}

....

...thought (danger)....

 

for a multi-user webapp like ussrp, should the controller spawn new processes (java) for each fill request (cgi-style)?

 

surely you have a best practice here...

 

...maybe a third variation would be to have a non-static version of the FillManager.

 

thanks!

fyi - issue was not jasper lib. issue was over utilized hardware (RAM). that is a good thing :-)

 

with 100MB RAM, jasper/tomcat/ussrp handled multiple simultaneous requests very well.
