AWS CloudWatch Insights Console increased latency

In the last week or so the cloudwatch console started taking a ridiculous amount of time to load. I recall it taking 3-4 seconds but now it is taking 10+. To repro, just try and hit this url if you are logged into the console:

https://us-west-2.console.aws.amazon.com/cloudwatch/home?region=us-west-2#logsV2:logs-insights

Was there some change that caused this additional latency? I'm seeing the same results on two different internet connections.
