What I'm wondering, as my hosting subscription is coming up for renewal:
1 - does having a server based in Australia make much difference to speed? 2 - does Google penalise slower sites? 3 - does Google take into account that if you have a .au domain, it should speed test for Aussies?
Basically, trying to get advice on whether it's worth moving hosts - the few website I've found discussing it try hard to push you in a particular host's direction, and then you see their affiliate code, which makes it harder to validate :/
Yes, in general, your server should be as close to your customers . . . but if you're calling into a lot of backend services to do flight searches, you may also want your server to be closer to your backend services (maybe they're in the US).
Second, choosing an AU provider might help to bring the the TCP round trip time, but in most cases, it is your application itself that is the bottleneck. You can test the pin times yourself, and I am think providers in US West coast and Singapore can give a reasonable sub 150ms ping time.
