Re: "benchmarking" memory usage

AFAIK Perl does not give back memory to the OS. So on Linux, if you put your code to benchmark in 2 different scripts, for each of them, just before exiting, you can get the memory used by your code in /proc/$$/status.

actually, I was thinking about a similar aproach but using fork and Proc::ProcessTable --> Memchmark	[reply]

This came up recently, but depending on the OS and your `malloc(3)` implementation you may see your `perl` process size shrink when `free(3)` gets called or you might not. Might be interesting to see a table of `$^O` / `$Config{usemymalloc}` / "will my process shrink?" across some different combinations. -- We're looking for people in ATL	[reply] [d/l] [select]
