Kali Linux Working Slow on a HP Elitebook Workstation!!

Well,its so weird for me having such issue.Linux made me dissapointed with its performance in front of my expectations.I have to addmit that it works good but sometimes I see it a bit slower working ,on opening and closing sth,and when I click on the icon that shows the applications thatsss the permanent action that is alwayss ssloww to show. Dont know why!? I love my specs of my workstation its i7,64bit,anddd it has 32gb RAM(400gb ROM).It's making me think twice about having kali as the primary OS installed on my pc.Any idea why do I have this issue?Any idea to get rid of it,I really hate slow actions in general.

Thank you!
