I'm trying to test using jsreport for our Saas application to replace our current reporting system , and i'm having two issues

1 - Poor performance.

2 - I cannot execute multiple rendering at same time getting this error.

An error has occurred when trying to initialize jsreport, seems like there is already a server running in port: 5488 (2). listen EADDRINUSE :::5488

Here is the code :

        var rs = new LocalReporting()
                .Configure(cfg => cfg.FileSystemStore())
                .UseBinary(JsReportBinary.GetBinary())
                .AsUtility()
                .Create();

            
        var report = await rs.RenderByNameAsync("REPORT-NAME", myData);
