Google app engine slow TTFB

I started looking at using Google app engine as CDN, but their TTFB is very poor开发者_运维百科. Can I do anything to reduce the response time of static content?

Google app engine isn't designed to be a CDN, it's a platform for you to build webapps on. If you're looking for a cheap CDN in app engine, I suggest you use something else.


The only thing I would like to add here is: Not all CDNs are designed to improve TTFB. In fact, 9 out of 10 will contribute to the delay - not help solve the issue.

To affect TTFB you need to kick off browser parsing as fast as possible. To do that, you have to reduce HTML processing time - which is your main delay factor.

I recently wrote a post about it, you may find it useful: http://www.incapsula.com/the-incapsula-blog/item/809-using-cdn-to-improve-seo-and-ttfb
