UUID/GUID performance

Summary

The transcript discusses the performance implications of generating unique IDs in software development, specifically highlighting the potential latency caused by system calls when using methods like `new Guid()`. It warns developers that generating randomness through the operating system can be expensive, especially in high-iteration scenarios like loops. The practical recommendation is to consider alternative ID generation strategies such as Ulids or sequential IDs when full cryptographic uniqueness is not required.
