[solved] Difference between 2 cpu, 4cpu and 8cpu?

[roycerus]

Hi,
I just installed litespeed. My admin says that we need to get only a 2 core license as we are using the amazon cdn and 2 core would be enough to deliver the data - in any case the rest of the 6 cores will be used to process php.

I am unsure if that is the best option. What exactly is the difference between a 2 core, 4 core and 8 core license - I know it says that it's optimized for 8 core. But what kind of optimization and results can I see if I invest more to get the 8 core license?

We are heavy php user and my server is a dedicated http server - quad core Intel(R) Xeon(R) CPU E5320 @ 1.86GHz

Kindly clarify.

Regards,
