Created attachment 36421 [details] This image illustrate the slowness on open response I have a problem with JMeter when I want to see the response using view result tress, if the response has a huge text (essentially JSON) I wait about 1 minute to open this response. see the attachment.
Hello, The gif does not show something obvious. Is your JSON code without any space ? If so, it's a known issue due to a JDK bug: View Results Tree may freeze rendering large response particularly if this response has no spaces, see Bug 60816. This is due to an identified Java Bug UI stuck when calling JEditorPane.setText() or JTextArea.setText() with long text without space. If it's not the case, please show the request so that we're able to reproduce.
