Drop your before / after numbers plus the rules that moved the needle.

Template that helps everyone read at a glance:

Site type        : WooCommerce store / business site / membership / other
Theme            : Astra / Kadence / Divi / Elementor on Hello / GeneratePress / custom
Active plugins   : ~25 (or whatever)
Hosting          : Kinsta / SiteGround / WP Engine / VPS / shared
Before TTFB      : 720 ms (homepage, mobile, regional)
After TTFB       : 280 ms
Hottest rules    : "skip Yoast on /cart", "memoize wc_get_product on category pages"

Reading half a dozen of these is the fastest way to learn what actually works on plugin-heavy WordPress. The rule library generalises from these threads.

If a rule didn't work, post that too — failure cases sharpen the library more than wins.
