Forum Thread: Kali Running Slow

its cuz you didnt give it that much of memory that it should have....

yes oracle VM

Those specs should be plenty, mine has 2 cores and 2 gb and it runs great for those specs. What are your computer's specs?

Try giving it only 2 processors. It may seem weird but if you use more processors than what your PC has than you will run into it having to emulate said processors.

Hello Everyone, I've Installed Kali In Hard Disk(It's My Only OS), But It's Slow To Boot Up and Run Applications. Ram 8, CPU I7. How To Speed Up ?

Try a lighter desktop environment, like XFCE or LXDE. Should free up some system resources.
