Description

Hi GoogleChrome!

I'm only assuming at this point since I haven't really put too much time into this as perhaps this steps outside of Lighthouses' scope. However, I've noticed that the audits don't mention too much about SSL handshake speed.

After reviewing various methods which are out there to improve the handshake speed such as; Enterprise SSL use; strict host resolution; the use of SSL stapling and caching; and so on.

What I am finding is that my test results come in good overall but since I test under real 2G environments the handshake is the biggest part of the process which slows everything up. I was wondering what are peoples thoughts on this?

Regards

James

Research direction
Investigate the Lighthouse codebase, specifically the existing performance audits (e.g., in lighthouse core/audits/). Look for any existing SSL related audits or hooks. Review the discussion in the issue comments to understand what specific metrics or suggestions were proposed. Consider implementing a new audit that measures SSL handshake time using Chrome DevTools Protocol's performance metrics.
