Curious if you think fibers vs async/await is still in this zone (amongst experts). It seems fibers are objectively better. But I'm no expert*

some of the STL is easy to improve on. For example, std::unordered_map performs poorly due to pointer stability requirements in the standard. Most performance sensitive C++ codebases will use something like abseil's hash maps instead.

The runtime performance and the language are deeply linked. None of the dynamically typed runtimes you mention are actually performance competitive with JVM languages.

Hi Nikita. Can you share any of Neon's techniques for minimizing noisy neighbor issues in the multi tenant storage services? Thanks!
