This is not packets per second

This is packets per 20 ticks. And 20 ticks can take really long if the server is lagging. Please consider using a better algorithm and better data structure for storing packet count. What about an array deque?

What about an array deque?

I never use php-ds

[SOF3]

you don't really need php-ds to create a deque though. You could as well just reinvent one yourself on an array :)

May it be a better idea to count the moment you receive a packet? Otherwise it might be too late.
