Negligible Pool Filter pressure. Is that bad?

I have a Hayward cartridge filter and Hayward dual-speed 1HP pump. The pump is overheating and turning off all the time now (not sure what is the issue but thinking of replacing it rather than fixing it as it is old). In the meantime, we are running the pump at half the speed (it is a dual speed pump) which does not cause overheating until we fix or replace the pump. But running it half the speed reduces the pressure on the filter from 12psi to almost negligible (2-3PSI maybe). I know high pressure is not necessarily good, but is low pressure also a bad thing? I realize not as much water being pumped as quickly, hence the low pressure. We're running the pump almost 24/7.
