I did a quick memory usage check on gmpc today, and this is the result I got: (I’ve disabled ssl in libcurl to save 1/2 a mbyte and fixed a weird 50k errorStr in libmpdclient)
This is starting gmpc, connecting to a mpd daemon (with a 14k song playlist) and skipping a few songs. I think it’s a very nice result (and gmpc uses even less memory then ncmpc.)
