My website is too slow in China
My website is hosted in singapore and loading at decent speed in some parts of China but not elsewhere. I used https://www.websitepulse.com/help/testtools.china to test speed in guangzhou, shanghai and beijing. Which shows that guangzhou is quite fast while the other two is only sometimes fast.
I have read https://www.digitalocean.com/community/questions/cannot-visit-my-website-from-china and removed any google api based jqueries including raty (my app is built on ror).
I even removed bootstrap carousel. But still v slow in china. Could it be that we are using gmail based email to send notifications? But surely this should only affect the mailer relevant pages not the whole site? Our images are stored locally too so i cant quite see any reason for being slowed down by the chinese firewall..
Any suggestions or sharing experiences would be appreciated thanks!
