I'm really confused.

I have a fairly international website geared towards English language learners, with Google Analytics and AdSense and links to share on Facebook, hosted on Digital Ocean here in NYC...

and, without designing for it, China has been my #1 source of traffic and revenue for many years now, simply because they're the #1 largest population of English language learners.

It seems to be working fine. I mean, maybe my share of Chinese traffic could be even bigger, but does anyone have any hard numbers showing this is a problem? Or are Chinese users aware of slow loads but just put up with it?
