FastReport.Prepare() VERY slow

Rexxrally

We are using FastReports to email out invoices in PDF format.

When the code hits the FastReport.Prepare() line, it takes about 15 seconds to return.
Is this normal? Is there some way to speed this up?
String together 100 invoices being emailed out, and it causes our webpage to time out before it finishes.

We are using FR 2015.3.1 and VS2010.

Thanks

if you're using dotnet 4.5, use async await for long running task

private async void createPDFandEmail()
{
    await Task.Run(() =>
    {
         //FASTREPORT CODE
    });
}

No, we're using .Net 4.0.

We're finding that upgrading our app to 4.5 is proving rather difficult.

in .net 4.0 : you can use Tasks Factory

in .net 2.0/3.5 : you can use threadpool

public void RunInBackground()
{
    System.Threading.ThreadPool.QueueUserWorkItem(DoSomething);
}

private void DoSomething(object stateInfo)
{
    //running in background thread
}

I am facing the same problem.

When I tried to generate a particular report ,the fast report.prepare() gets timeout and making service down.

I removed a property in datasource which was not part of api response ,then the solution is up and able to generate report fastly.

I am not sure what is the exact issue behind it. Can someone help to find the root cause?
