This is not a new topic on my blog<\/a>.<\/p>\n

Today, I\u2019m trying to open, save and edit three documents that are each 50 megabytes in size. My MacBook Pro has 4 physical cores running at a base 2.6Ghz and 4 logical cores (via Intel Hyperthreading) yet Microsoft Excel still only uses one of those cores for its processes. We\u2019ve had Core2Duo chips for 10 full years. I don\u2019t understand why this is still a thing.<\/p>\n

Note: on the screenshot above, applications that are multi-threaded will use over 100% because it\u2019s each core so a video encoding process might use 800% CPU percentage. It\u2019s juts how the iStatMenus developers chose to write their application. You\u2019ll notice Excel using 100.1% but my system is 84% idea.\u00a0
