- Subject: high memory usage by d21
While running GCC tests I happened to catch a glimpse of some d21
processes with much higher resident memory usage than others, on
the order of 1GB to almost 2GB. Is that normal?
Below is a snapshot I took. I saw a few others that were higher.
(It's not causing any problems for me so I'm mostly just wondering
if it's a known issue or some hidden inefficiency that might be
worth look into).
