3. JSReport local performance

JSReport local performance


  • Ah ok, need to fix this in the docs. Please use JsReportBinary.GetBinary(). Thank you for notice.

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

  • Even for the second run?

    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.

  • Ok. You have some kind of complex html I guess right? In this case switching to web server doesn't help so much. It is significant for the small reports.
    Can you paste here debug logs? Get it this way:

    var logs = "";
long startTime = invoiceReport.Meta.Logs.First().Timestamp.Ticks;
foreach (var l in invoiceReport.Meta.Logs)
{               
    logs += $"+{Math.Round((double)(l.Timestamp.Ticks - startTime)/1000)} {l.Message}\n";
}

    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.

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

  • Thank you. I see in logs that it spends the most of the time in phantomjs which is rendering the pdf. That is something we cannot influence.
    However could you share the html input file?

    It should be available during the rendering in the temp

  • I get 700ms if running this code with provided html

    var rs = new LocalReporting()
                .KillRunningJsReportProcesses()
                .UseBinary(JsReportBinary.GetBinary())
                .AsWebServer()
                .Create();
await rs.StartAsync();

var testingContent = File.ReadAllText("test.html");

Func<Task<Report>> render = () => rs.RenderAsync(new RenderRequest()
{
    Template = new Template()
    {
        Content = testingContent,
        Engine = Engine.None,
        Recipe = Recipe.PhantomPdf
    }
});

//warm up
await render();
//messure second
var now = DateTime.Now;
await render();
var totalMs = (DateTime.Now - now).TotalMilliseconds;
Console.WriteLine(totalMs);

await rs.KillAsync();

    We could get to like 300ms if we add support for reusing phantomjs instances over requests. This is already supported in the full jsreport. It is just missing in the compiled binary used in jsreport.Local. I've submitted improvement request to which you can subscribe here.

    If the 700ms is an issue for you and you need to solve it right now, you can always startup full jsreport or use jsreportonline and connect to it using jsreport c# client. Both support reusing phantomjs instances.

    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!

  • Great! Thank you. Glad to be helpful.

    Hi Jan, is there a github issue to subscribe to for the UseBinary performance relative to AsWebServer? We are going to be deploying a single report with that approach soon, but will ultimately be purchasing and running 20-30 reports by spring time. So, we are curious on timing, or if it would make more sense to use a standalone server at that point. Thanks!

  • @dmTech04 Here is the optimization issue. Running standalone jsreport instance is usually better in architectural and scale aspect, but the jsreport.Local is on the other hand more convenient....

    Thanks @jan_blaha. I am coming to the same realization. :)
