> The usual application where GC is most relevant is connected to 10s of services over some network protocol, and often has to load each business object/entity it operates on into memory to check permissions, sometimes even issue another network call, etc. Loading that entity from a list of pointers is absolutely no bottleneck in such a setting, at all - the way you might speed up the app is doing the work on the database itself, which is already written in some low-level language, efficiently.
No my example isn't a complaint on it using GC language. It is that it is loading and unloading business entities multiple times and doesn't take into account that operations could be done linearly much faster instead of hunting a field in object graph to accumulate in various ways. That is how e.g. numpy works if you make sure that the array you do your operation on is of the same type.
> Your anecdote is just a badly written application, I have plenty examples of very performant ones written in managed languages.
Yes following the ideas of what is considered SOLID principals. The objections isn't managed vs. unmanaged it is going full OO and not giving a shit about how computers work.
