A single awk script is probably way more efficient than the multiple awks and sorts and echos and what not you had before, that's why I'm proposing it.
If you can fork the code from top to give you exactly the output you want, it will of course be more efficient still, but IMHO probably not worth the programmer effort.
Maybe if you could add a module to top to produce XML or CSV or something else more machine-readable, that could perhaps be worth it.
i see that using a single awk would be faster, but im still working to uderstand how to doit.
eventually i hope my script is a while loop (needed only for dzen) and an awk calling a script file with the -f parameter.
and what you mean by "if you could add a module to top"
