Some ideas that I've not seen mentioned before yet: 1) perf top - to see where the system is spending time as a whole (and if you need to drill down on a process you can do perf top -p $PID). 2) latencytop - as long as your kernel has CONFIG_LATENCYTOP 3) iotop - if your version is new enough then the -o option will hide idle processes, otherwise just press 'o' when you get the main display. Best of luck!
