Menu Meters

Problem: My mac is slow but I don't know why.

Solution: MenuMeters is a small monitoring tool that let's you see where your resources are going. I limit mine to just Network, RAM and CPU usage.



Green line = Network download usage
Red line = Network upload usage
Pie = RAM usage
Percents = CPU usage (I have 2 CPUs)

Cost: Free
