Yeah, I’m sure my Claude generated email client could be even faster if I wrote it by hand. Modern computers can retire billions of instructions per second per core. All operations that aren’t downloading or processing gigabytes of data should be instant on modern computers.
Claude’s toy email client gets closer to the speed limit than Gmail does. Why is Gmail so slow? I have no idea.
I find the sweet spot is to take LLM generated code, then profile manually and heavily supervise or hand implement specific improvements.
You can also let the agent use a profiling tool. It probably cannot beat you, but does find and improve a lot of things for sure.
