Does Lua not have the startup time issues of Python/Ruby? If it does, then to counteract the lack of threads you'd probably use a coroutine-based system like gevent and Python's greenlets.

- chubot 15y agoThat's a good comparison to make, but once you have a Python program or Ruby program importing 20 packages, each with several modules, then it gets really slow. Like 100-500ms, which is more work than the "real" work of a handling many HTTP requests. Bad packages can do arbitrary computation at import time. To be fair, I haven't run any Lua programs with 20 packages... AFAIK Lua didn't have a module system until Lua 5, and it's not as capable as Python or Ruby's.
- silentbicycle 15y agoNo, it doesn't. It also has vastly more efficient coroutines.
