Hi,
I've set up a custom domain for my service and I find that when accessing the service via that domain it is significantly slower than accessing it via its $
PROJECT_ID.appspot.com address. I have determined that it's not an issue with DNS as the difference in latency is still there when using the resolved IP addresses directly.
The slowdown is very noticeable: it varies from 2x to 10x slower on the custom domain, and the delay occurs in the period between the connection being established and the first byte being sent.
Also note my app engine service is running in Sydney.
Is it possible I've misconfigured something? My DNS is CNAMEd to
ghs.googlehosted.com, but it seems to me that using custom domains for routing is simply really slow. Is there anything I can do to improve the latency here?
Cheers,
James
