My ssllabs overall rating is "A+", but the “Test duration" is too long, I tested other sites are generally about 60-80 seconds, and my test duration actually more than 160 seconds.
How should I accelerate test time?
You can't. The speed depends on the distance between SSL Labs servers and your server.
SSL Labs connections are intentionally spaced-out so as to reduce the load on the target server. I have a plan to reduce the number of connections we use in the future, at which point the test will be faster.
