Linux command line to check TTFB

By Claude Sonnet 3.7. It's just curl.

Keeping it on the blog because it's useful and certainly I'll not remember this command at all.

curl -s -o /dev/null -w "Connect: %{time_connect}s\nTTFB: %{time_starttransfer}s\nTotal: %{time_total}s\n" https://yourwebsite.com

TTFB: time to first byte. I got a lot of this problem with WordPress websites.
