Looking at your post count, it's possible that this is your first C7. In that case perhaps your question isn't about the speed of the cranking but rather that it takes a couple of cranks before it fires up? If my supposition is correct, be aware that that is perfectly normal behavior, aimed at building oil pressure before the engine fires up.
Just thought I'd check this before you start possibly chasing your tail with the battery...

Don’t buy a battery until you get yours tested. I’ve had Delco batteries last for many years. It’s the nature of direct injection engines to crank a few seconds. Add cold weather and add a few more seconds.
Batteries do last more then 3 years. I had a c5 go 9 years.

You can always check/clean the battery-cable connections, as well. I just had a friend with a loose cable at the battery and it was driving him nuts... but, he'd never checked, just eyeballed it. Another possibility. All the best!
As for the longevity of OEM batteries, it's ALL over the ballpark, even for the same car, same year. My C5 which I ordered new and used as a daily driver barely went two years; a friend's all the same but went at least five years and was still going strong when his wife took the car in their divorce.

The battery on my 2014 Z51 convertible lasted two years and was replaced free under the warranty. The 14's had the best and longest warranty of all the C7 model years.
