Fun thing is that this started because somebody claimed that Cloudflare is faster than Vercel. Then somebody who knows what they are doing did benchmarks that showed the opposite. And then worked with Cloudflare to make it faster
They might flip the emergency switch that burns a little more money to improve the cold start, schedule more CPUs to each V8 process or remove the `sleep(100)` somewhere in the code. I kinda doubt that they have actually made any code improvement but just a marketing stunt that make everything seems to be faster for a month then everything will be just as slow as it is, or they are buying time to actually improve the code.
And nobody on the benchmarks mentioned that Vercel runs it on 2 gb. Instances ( and much more expensive) while Cloudflare is competitive with 128 mb. instances.
I guess that's the difference between building on top of AWS and actually building your own infrastructure.
Theo knowing what he’s doing died for me when he did a dive into this fancy new data format OpenAI started using to stream responses from the server and how wasteful it is (SSE) (and this was in 2025)
I don’t except everyone to know everything but it made me very careful about differentiating Theo-the-engineer from Theo-the-social-media-dude.
