How to reduce browser launch time?

reportSlowTests should not affect browser launch duration. Maybe something else changed which slowed it down?

But now that I think of it, maybe that tiny change caused Playwright's Babel transpilation cache to be outdated, so Playwright will re-transpile everything again? Just guessing a bit. But if that's the issue I'd expect it to be a problem only once.

What version of Playwright are you using? Maybe worth trying to update to the latest (if not already using that)?

not enough info really here, perhaps you're running many API requests prior to launching the browserContext?

Which browser are you using? Which version of Playwright?

My suggestion is change your url to something link google dot com or amazon dot com and see if still have delays? If yes next item worth to consider looking: Do you have any antivirus scan actively monitoring process launch?

My tests also have a long delay. It is tied to the condition when playwright thinks that your page is loaded. in page.goto, you can use options.

in the options there is a waitUntil parameter. You can try changing it to domcontentloaded or load. it solved my problem. https://playwright.dev/docs/api/class-page#page-goto

With connectOverCDP test are running on already opened chrome browser https://playwright.dev/docs/api/class-browsertype#browser-type-connect-over-cdp

using Playwright 1.39.0 version and chrome browser. I have tried other website also and facing same issue. I didn't use anti virus software
