Maybe a silly question but is there a way to know the peak memory (not the total allocated memory) occupied during the execution of a julia function? (under Windows if possible)  
Thanks.

The unix `time` program can report this (sometimes with an extra flag, such as `/usr/bin/time -l`). I don’t know of the corresponding Windows capability.

Thanks for the reply. /usr/bin/time would certainly be an option but I thought that the GC would also keep track of the peak memory.
