hi all, I'm really not sure where to start troubleshooting this. If I use a computer to access our RT instance, then the speed is good. If I use any iPhone, then the speed is terrible. 6S/5S/4S iOS7/8/9 - all terrible. By terrible - I mean that the front page might take 10 seconds to load. If I tap the username field, it might take a further 10 seconds before I can enter text. Each and every tap / submit / etc is unusably slow. The key is a 2048 RSA which should be OK on an iphone.
It *feels* like a site that's using horrible javascript, making the browser unresponsive. But on an iPhone I really have no way of testing this (well that I'm aware of). We're running it on nginx, TLS, self signed cert - signed by an internal CA that is trusted by the phone. I've tried things ranging from spdy (html/2 not supported on iphone), loading the pem with all of the certs in the chain, enabling caching of static objects - no difference. Just to be clear - it's fast on a regular PC / browser. Just slow on phones (mobile & regular interface) - slow regardless of location (i.e. wifi in the office to the server, 4G... no difference). any ideas where I should look? or what do i need to tell you... to try and get help? Thanks! Chris
