That's a lot more threads than iTerm uses for me, but it's less memory. Typically my work computer (a 2015 15" MBP) tends to be bottlenecked on RAM, too. 16GB sadly is pretty much the minimum viable amount of RAM for me to do full stack development these days.
I've maxed out my 64GB a few times and have seriously weighed upgrading to 128GB. Running all the development environment on my localhost (where I'm the actual sysadmin) is really handy if your sysadmins are too busy to help you with their business side of things.
