"My site is slow" is the hosting equivalent of "my car makes a noise." Let's isolate it methodically. Start at the server, work outward:
1. Measure TTFB first.
curl -w "DNS %{time_namelookup} Connect %{time_connect} TTFB %{time_starttransfer} Total %{time_total}\n" -o /dev/null -s https://yoursite.com
High TTFB = server/app problem. Low TTFB but slow feel = front-end problem.
2. If TTFB is high: check for a missing page cache, a slow plugin/query, PHP version, or an oversold server (test at peak vs 3am — big gap = noisy neighbors).
3. If TTFB is fine: it's images, render-blocking JS/CSS, no CDN, or too many third-party scripts. WebPageTest's waterfall is your friend.
4. Always check from multiple locations — "slow" is often just "far from the server, no CDN." 🌍
Post your curl line above and your stack, and the thread can usually spot it in one reply. What's your current Total time?
