Tracing JS Performance

on YouTube ↗33m

" summary

A demonstration of dynatrace HX Edition claims it records exact browser activity in Internet Explorer: per-event transactional traces, DNS/connect/server/transfer breakdowns, and CPU/JavaScript versus rendering timelines that show which JS calls schedule layout or repaint. The tool exports entire sessions for offsite analysis, integrates with Selenium-style scripts to mark test phases, ships as free v0.3, and reports real deployments where it found and fixed performance regressions — the tracing agent installs as a browser plugin and the export/automation features work.
