Dev tool to count how many times events fire with CPU usage and sort them from most to least. Has an ignoreList table that you can edit. Made this just out of interest what events are spammed the most during raids. Type /ecount to display event counts (/ec shortcut works if no ElvUI installed).
Important: If you tick the CPU Profiling checkbox on this addon you must remember to turn it back off when done, this addon will remind you it's on at logon but if you disable the addon and forget to turn it off your fps will suffer. It's an account wide setting so turning in on or off will set it for all characters..
