If my Macs couldn't keep up with my typing, I'd have kicked them to the curb a LONG LONG LONG time ago.
My theory is that the Intel macs generate too much heat for the chassis to handle (I'm currently on a 16" 2019), especially when being used by IntelliJ in projects with many files, having additional dev stuff running in the background, and with an external monitor connected.
Additionally, I perceive more lag on the Mac itself than on the external monitor, so I think there is a component that is due to the slow speed of the Macbook Pro display.
No, seriously, what’s the secret?
Back when I got my first Mac (2012) I was plateaued at 80-100 wpm. From there, it was an accumulation of intentional practice for fun and enjoyment.
You are, of course, wrong. Cursory googling will show average typing speed to be about half the figure I noted. I've never worked with anyone who typed as quickly as I can, and I've been working quite a while.
But hey, at least you got to drop a dig in about adverbs, so you've got that going for you.
I'm rolling
90 WPM is ok, certainly above average. But please don't take it personally, I was just scrolling through the comments and saw what I thought was a typo, and if not, thought I'd share my perspective. 120WPM can be considered "fast".
If 90 WPM is "very, very fast" then what about those at 120 or 150?
