ZP slows down computer a lot when only using 15% CPU

[Cyrix]

I purchased a new i7-4790 computer dedicated for running ZP.
Now it's running total of 30 threads, using less than 20% of CPU.

However, the whole computer is getting very slow.
Opening other applications like notepad, chrome, or even a folder takes forever.

Is there something wrong with my computer, or it is normal?
I remember in my old computer, running ZP didn't affect the speed of things outside of ZP.

What about your RAM?

Ram using 5 G on a 8 G machine.

What do your projects do? Do they utilize hard drive a lot? In this case opening a folder can take a while

From my experience it is not the best way to run ZP on the same PC you work on. It will always hit same spikes in resources and you will always get some freezes here and there.

Probably not the hard drive.
Even webpages don't have enough speed to load.

Bought 32G for this machine, and it got faster.
But another problem occurred:

Is it HDD or SSD (with SATA 3)?
