I run Excel 365 (part of Office 365 package) on a Surface Book with latest version of Windows 10 Pro (10.0.18363 Build 18363), Processor Intel(R) Core(TM) i7-6600U CPU @ 2.60GHz, 2808 Mhz, 2 Core(s), 4 Logical Processor(s), 16GB RAM. Excel used primarily for complex financial modeling (typical investment banking M&A and private equity investment models). Excel opens quickly and for the first 15-20 minutes works perfectly. However, after say 20 minutes, there can be a 3-5 second lag between inputting a value (number or formula) in a cell and the program executing that input. This is exasperating and renders the program unusable. The only solution I have found is to close out all programs and reboot the laptop, which is hardly a practical option. This solves the problem only for another 20 minutes or so, when the problem reoccurs. I would appreciate any advice on how to deal with this. I have not found any recent articles on Office Support. Thanks.

I have tried with both a new spreadsheet as well as working with an existing model -- no difference. I will screenshot the usage info and post when I next have the program open.

Here are the screenshots showing CPU usage and performance. I am currently using the program and experiencing the lag. @wolw6789
