CDN and TTFB

[El_Foodie]

Hi there,

I own a Joomla site situated in France and I'm aiming at customers in France, USA and Australia. The site is on dedicated server, paged delivered with nginx in http2. I tried to use a CDN (MaxCDN/Cloudfront) to improve TTFB on my sites in other countries but figured out it was a bad idea since I see no improvment at all.

with CDN
https://www.webpagetest.org/result/170324_67_5MDC/ (AU)
https://www.webpagetest.org/result/170324_QA_5M70 (US)
https://www.webpagetest.org/result/170324_NZ_5NQM/ (BEL)


without CDN
https://www.webpagetest.org/result/170403_ET_1DMM/ (AU)
https://www.webpagetest.org/result/170327_32_Z49/ (US)
https://www.webpagetest.org/result/170327_16_N44/ (BEL)

So I suppose this is because joomla create dynamic pages which are not hosted on CDN but generated by my site, am I right ?

1./ Do you know any solution that would improve ttfb in my case for Australia and US, because they are pretty crappy as compared to Europe ? Do you think Cloudflare would do something ?

2./ Do you any advice I could do to improve the load time in Australia, with or without CDN, because it is very high especially in first view ?

Thank you for reading,

Cheers,

Fred
