Can the operation of one user affect the entire Service Cloud?

Summary

Is it possible that the entire service cloud will slow down if you perform a time-consuming search in a report, such as a full incident search?

Hi,

Let me ask you a rudimentary question.

Is it possible that the operation of one user slows down the service cloud?

Extraction may take some time when performing a full search of incidents from Analytics.

I am worried that the impact will spread to other users.

Thanks
