<![CDATA[rendering a report of large data]]>Hi,

I am trying to render jsreport with around 100k records (pdf using phantom-pdf and also tried with chrome-pdf) from my application using jsreport client. It is taking longer time to generate. In the meantime, session gets timeout in my application and hence report not getting rendered/downloaded in the site.

Is there a way to improve the performance and avoid session timeouts.

This is very critical for my site. Please help me to get this done.

]]>https://forum.jsreport.net/post/2768https://forum.jsreport.net/post/2768Invalid Date<![CDATA[Reply to rendering a report of large data on Invalid Date]]>Thanks.
I see you render 2318 pages and jsreport spends the most of the time in phantomjs process during converting html to pdf.
There isn't much to do. You can try to simplify your css styles but the rendering of such long pdf will always take a while.

I recommend you to re-architect your UX during rendering such big pdf.
Make the action a background job.
