Jon Degenhardt <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] | |m --- Comment #5 from Jon Degenhardt <[email protected]> --- I have noticed meaningful performance degradation after associative arrays reach about 10 million entries. I gave some GC related numbers in this forum post: https://forum.dlang.org/post/[email protected] In addition to GC stats, it appears likely that resizing the underlying array will be costly at these numbers. Having an ability to reserve capacity for a minimum number of keys may address this. --
