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!

perfect Thanks!

Here is a sample log output: (I am not killing rs.KillAsync() and kept it running and see an improvement).

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.

@projectmavericks @jan_blaha @bjrmatos I tried putting the JSReport temp to different drives and folders but it seems that it requires "Local System" privilege irrespective of that. Can you please confirm what exact privilege it requires from "Local System" to run this successfully when configured on IIS App Pool.

@projectmavericks setting it to "Local System" and "CORRECT APPLICATION POOL" (so silly of me using old app pool due to clogged Dev environment!!) did the trick! phew......but not sure the "Service Account" that we are creating as part of Deployment will get that kind of privilege and hence I am asking what exact privilege is JSReport looking for when deployed on IIS.

@projectmavericks don't worry fixed it.....now need to see what to do with "Local System"? Do you have any suggestion on the least privilege the utility can work with?

@projectmavericks Can I turn on some verbose logging to find out where JSReport is failing? Why it is able to write req file but not meta file?

@projectmavericks yes I have tried all the tricks to no effect! What I found is that on local environment I was able to replicate and fix the issue by running the AppPool as per the Local System identity but it doesn't work in Dev and other server environments.

@projectmavericks well it is creating req<<>> files but not meta<<>> file, so not sure it is firewall but more of permission issue with IIS from my analysis so far. what kind of privileges is required on IIS? What are we looking for when JSReport binary is used by ASP.NET core Web API?

Unhandled Exception ---> System.AggregateException: One or more errors occurred. ---> System.IO.FileNotFoundException: Could not find file 'd:\temp\meta509ac238-0eda-4050-a5a1-cdba6e3218ec'.

IIS has Local System access still same problem. Is there anything else we need to do? Why is it writing request but fails to write meta file??
