Thanks Jan! I was able to bring down performance also by using the web server to an acceptable level. You guys are just amazing and community is brilliant at posting quick reply. I am so happy that I choose JSReport for our reporting problems!

Well it is not that complex a very simple template. The thing is I am using DI to inject the instance and can't exactly measure time as you suggested. I will still give it a go and share the logs.

Yes first run ~7secs, second run ~2 seconds same as binary in my case....and even I am not killing the process. If I kill then ~7-8 seconds every request.

Thanks for your quick response but I see better performance with Binary then web server in my case!

Hmmmmm....I can't seem to find JSReportBinary.GetStream() method in jsreport dlls.

I have been using JSReport to convert the html to pdf with Phantom PDF recipe and jsreport.local and jsreport.binary packages.

I have noticed that it takes almost 3 seconds once warmed up to complete the conversion. Can you please suggest some improvement that I can do to improve its performance to ms?

@jan_blaha Thanks for your clarification.

Instead of "Local System" you can see the "Load User Profile" to true for IIS 7+ on your server, so that your "Service Identity" can create the JSReport socket files in "User Profile" directory and it doesn't get into any other temp folder where you won't have access.
