[dundee] Investigating resource hungry processes

[Marcel Hecko]

Hi Iain,

we are using `iotop`, `ps` (ps -efH) and `lsof` (lsof -i for sockets) to
digg into the resources usage on the system.

It's usually a question of CPU and I/O usage than memory bottlenecks which
make mess.

Sincerely,
Marcel
