lsphp4 using high CPU

[anewday]

Is it good to change the priority of lsphp proces using spri and if so, which value do you recommend? Still puzzling as to why the cpu still spikes so often.

I don't think the process priority can affect the performance much, as long as the server load is not high and PHP is not in a dead loop, the CPU spikes are normal due to the fact that LiteSpeed only use a handful persistent PHP process to handle all PHP requests.
