Care to show links? I find hardly to believe that deallocation increase
performance...
Stopping program to perform memory scan and trashing memory in process
is faster? how so?
Or one doesn't have to stop whole program to perform scan but it must
issue synchronization on every pointer access is faster?
Language Rust is major point against GC. Language is designed with GC
in the beginning, but experience showed against it and they finally
dumped GC from language...
