The higher CPU consumption usually occurs when you launch Skype from your computer. If you come up with a laggy performance at that time, then probably Skype is consuming more processing power than needed.

But if this slower performance happens only once a month, then there are chances that Skype is looking for an update, which is triggering more CPU usage.

On the other hand, if this sluggish performance occurs every time you launch or sign out from the Skype messenger, then you’ll have to find out the real cause behind this.

Apps in the background

Running multiple apps along with Skype puts a lot of load on your CPU and RAM. And if you running apps that consume more RAM and CPU resources, then you’ll need to close them. Now there are two ways of doing this, directly closing them or ending the process in Task Manager.

Likewise, if you are running multiple messenger programs at the same time, then all of them will compete to grab as many hardware resources as they can to deliver better performance.
