ReactSiteConfiguration.Configuration.MaxEngines recommended engines

[debrouwernele]

Hi,

What is the recommended setting for MaxEngines? At the moment this is our configuration: JsEngineSwitcher.Current.DefaultEngineName = V8JsEngine.EngineName; JsEngineSwitcher.Current.EngineFactories.AddV8(); ReactSiteConfiguration.Configuration.MaxEngines = 35; ReactSiteConfiguration.Configuration.ReuseJavaScriptEngines = true;

On production we had the following error: JSPool.Exceptions.JsPoolExhaustedException. There's an average of 40.000 page views per day.

We also notice that the Memory keeps filling up. We need to recycle every few days to clear the memory.

Any help is appreciated.

Kind Regards, Nele

You have a leak somewhere, the default should be fine for most applications.

We have seen this before with the v8 engine, the cause is unclear. You may have better luck with the ChakraCore engine.

Disabling pooling will also work but has worse performance..
