It's not clear what exactly they mean by cold start. I just ran a simple test with a worker returning hardcoded html without external requests (on a free plan): 1. First run: time_starttransfer: 0.507267s 2. Second run: time_starttransfer: 0.035244s So it looks like at least some parts of the cold start taking much longer and aren't eliminated.

It could be due to cache warming?

Free tier is subject to lower quality-of-service in a number of areas. If you upgrade to a paid plan ($5/mo) you should see much better results. We probably should have included a discussion of this in the blog post... sorry about that.
