Overview panel
The panel is comprised of 3 part diagrams:
1.FPS
The Flames per second. The higher the green bars, the higher the FPS. The red chunks on the FPS indicate a long flame, which may be the result of a lag. (Animation rendering time exceeds the screen refresh time)
2.cpu
CPU resources. This area chart indicates which event consumes more CPU resources.
3.net
Each colored column represents a resource. The higher the pillar, the longer it takes to get it. The lighter-colored portion of each bar represents its wait time (the time it takes to send a request to the first bit to download it). The dark part represents its processing time (the first bit receives
Time to the last bit received)
The color of the pillars corresponds to the following:
