Based on Google Webmaster Tool ~ Site performance, my blog ~ JayceOoi.com takes 13.5 seconds to load (updated on Dec 17, 2010). And it is slower than 98% of sites. This is not a good sign because site speed is one of the factor in Google search ranking algorithms. So you will rank lower if your page speed is slow. But the question is how much?
I took 2 web pages to test ~ LiewCF.com (CloudFlare Review: Speed Up and Protect Your Blog) and JayceOoi.com (Download darkstone SuperRAM FroYo Android ROM for HTC HD2). For your information, LiewCF.com is using CloudFlare which has Globally-distributed network (CDN) while JayceOoi.com is hosted at HostMonster with WordPress Super Cache plugin only.
Based on the video above, CloudFlare does not seem to help much in improving blog loading speed. Maybe due to many advertisements and other add-ons. How is your blog loading speed? Check it out with the help of WebPagetest.
