WebView loadSnippet takes long time

[amichon]

When i load a snippet in the webview EWO it takes a long time (~2 seconds)

It takes 2 seconds after searching "gojs" after 22:13:50.376

Please find below the logfile of the Web server (flag -dbg 2)

Any idea about the cause ?

It depends on what you are doing in go.js. For example, if you have long running functions and are waiting (await) for them, you can simply block the main thread for a few seconds.

[amichon]

yes but gojs is automatically loaded by the function loadSnippet(). It is loaded from installation path, not from my project.

I will open a support request

[kilianvp]

Oh its sorry its from ETM. Yes creating a support request is a good idea.

[amichon]

after restarting the project or computer I no longer have latency

so there is no problem

[kilianvp]

maybe it was a websocket issue? the javascript code connects to websocket
