Edit: Does anyone have a version of top or something similar that works on the empeg?

Not sure what utils you have installed on yours, but in the absence of top, a combination of ps, sort, and head can serve as a "poor man's top" in the following combination:

ps -eopcpu,pid,args,rss | sort -rn | head -5

.
This will give you the top 5 programs in order of CPU usage. If you want to sort by memory size instead (flite is probably a bit of a memory hog!) do it this way:

ps -eorss,pid,args,pcpu | sort -rn | head -5

.
Or, just untar top out of Frank's ARM debian image.
