CloudFront is not only scalable, it also eliminates bottlenecks, but aims to speed it up.
AWS CloudFront is a service with low latency and fast transfer rates.
Here are some of the symptoms that may be slower when using CloudFront.
(This includes most problems.)
The requesting Edge may be receiving a large number of requests.
The edge server closest to the client may be farther than the web host server.
(Geographic delay)DNS lookups can be delayed.
There is not much of this possibility, but make sure the x-edge is in the "View in cloud front" state.
Cache may be missing.
Detailed troubleshooting is difficult because you do not know what the test is or what the condition is.
If logging is enabled, further troubleshooting is possible.
It is generally recommended to enable logging.
