Yes. & in the end my experience has been that you can write low latency code with gc, but only by expending more effort than it'd take to use manual memory mana

- pjmlp 3mo agoFirst of all it depends on the language, what GC models it supports, and what are the performance SLAs. Secondly if we are talking about something like real time audio, or sending the maximum amount of triangles per second, then there is zero memory management, the code should be allocation free across all the critical path, regardless of the language.
- whaleofatw2022 3mo agoAka 'follow JSF guidelines that still apply to C and not just C++'. I.e. all alloc should happen up front, functions should have predictable execution time, etc etc
- PaulDavisThe1st 3mo agoNot just allocation free. It needs to be page-in free too. And critical loops need to be cacheline friendly.
- pjmlp 3mo agoYeah, that as well.
