自從我開始付費20美金（Pro Plan）+5美金（APO）給CloudFlare後，我就很在意到底CloudFlare給網頁性能的提升有多少，是否值得買。
昨晚我把Pro Plan 取消了，原因是我發現CloudFlare可讓你的網站變慢！ 以下是我Submit 的Ticket詳情：
6 to 15times longer wait for CF to serve the first byte to Hong Kong traffic
- Pro Plan- Hosting: Kinsta, Hong Kong datacenter
- Test tools: GTMetrix, WebPageTest.org
- After figuring out the problem, in the DNS setting, the main domain is "DNS-only" until the issue is resolved
Details:
Since May I have been wondering why the google pagespeed insight suggest green (lab data) but in google search console (field data) the number or need to improve and poor increases. I then used GTMetrix to test my site url from Hong Kong, surprisingly the first byte takes 500~600ms, sometimes 1500ms. When I set the test server in Sydney, London, the first byte takes only 100ms. WebPageTest.org gives similar value. I then "turn-off" CF by setting to "DNS only", immediately the Hong Kong first byte time reduces to around 100ms.
Conclusion:
CF edge is working well with Kinsta if the traffic source is not from Hong Kong.
Since my major traffic is from Hong Kong, I will need to wait this issue to be resolved before resuming the Pro Subscription.
等待CloudFlare答復中。
