CPU: a b c. a=estimated cpu usage (system-wide) per second, b = cputime (app), c = gputime (app)
MEMORY: a b. a=private mappings (app). b=available memory (system)
FPS: a b. a=main window framerate (foreground window). b=display framerate
EVENTS: a b. a=cumulative input events to the window. b=cumulative input events on the display.
OBJECT: nothing
API: # of opengl calls (app)
DRAW: # of draw calls (app)
TRIANGLE: # of triangles (app)
VERTEX: # of vertices (app)
CPU note: The CPU values represent percent of total CPU capacity so if you see "cpu 43 0 0", because it's a dual-core CPU, that could mean one CPU is running at 86% and the other is mostly idle.
Generally seeing "cpu 50 0 0" would mean you've got one CPU "pegged" at 100%, so that may be a sign of a problem.
