htop

You can use htop to see memory and cpu usage of processes.

Disable threads

By default every thread is listed in the htop output. You can disable this by doing the following:

• Press F2 to enter the setup.
• Go to the Display options.
• Look for Hide userland threads and Hide kernel threads, and toggle them
• Press F10 to apply the changes.

This will hide individual threads and show just the main process.
