Can confirm. The CPU usage is really high even when script doesn't do anything (waits for pixels to be changed). When the code first start the CPU sits at 100%, then after a 5-10 minutes goes to 200%

This is CPU usage of two scripts from double core hetzner VPS. One with 5 accounts, other with 20. (The script with 5 accounts is running with debugger mode)
