[Bug] The final reports are slow to render

What Are You Seeing

I understand that the size of the HTML report file is larger when using 'newman-reporter-html'. In order to improve its load time, I push it to S3 with Cloudfront. While this method does make it faster, it takes a long time to render (I'm not exactly sure what the correct term is) which causes my browser to slow down for about 1-2 minutes.

Steps To Reproduce The Issue

Generate with the below script

Full Newman Command Or Node Script

newman run \
            postman_collection.json \
            --environment postman_environment.json \
            --reporters htmlextra \
            --reporter-htmlextra-export "$REPORT_FILE" \
            --reporter-htmlextra-noSyntaxHightlighting \
            --suppress-exit-code

Hey, @canle1404,

Apologies for the tarde response here - It's been a busy time.

This is an ongoing issue , one that's been reported a few times. I haven't made any huge changes to speed this up. There are a number of flags that you can use to reduce the amount of information that's part of the final report.

Do you need all the information for every single request, who is the report for? Do they need to see everything?

There isn't really anything that i'm going to be doing here in the short term, you can leave this issue open for tracking purposes if you'd like to see any progress made in the future though.

Thank you @DannyDainton

sharing workarounds:

1. first problem is syntax hightlighting 1.1 solution: use noSyntaxHightlighting flag
2. second problem is function formatXML and the RegEx parsing is to slow on big-lengthed rows 2.1 solution (aka hack) - rewriting final report before publishing to users: 2.2

   const rewrittenContent = inFileContent.replace(
       `return xml.split('\\r\\n').map((node, index) => {`,
       `return xml.length > 10000 ? xml : xml.split('\\r\\n').map((node, index) => {`
     );
     fs.writeFileSync(outFilePath, rewrittenContent);
