Yeah so far the performance is very close to my 10 core iMac Pro I use for day to day development. This is on a MacBook Air with no fan, and so far I haven't felt the machine even get warm even when compiling _and_ also running tests or importing data in other processes.

This is when running a decently sized Rails monolith w/ PostgreSQL & Redis, so a fairly typical modern Rails setup.

It's seriously impressive.

Does it mean you can no longer easily tell if a process has gone crazy and takes high CPU usage without a fan and you also can't even feel the slow down.

Totally broke my workflow: https://xkcd.com/1172/

I was wondering something similar. VSCode tends to fly off the handle every once in a while and the only way I notice currently is a subtle lagging and the fan spinning up.

Though recently I switched back to VIM so perhaps this won't be an issue anymore.

That is true in many situations, like a remote server. That's why we have top on the commandline, or iStat Menus. But I'm not sure if iStat Menus actually works on the new machines.

Those are passive solutions. You'd be looking at them after you realize something doesn't look right.

iStat or similar can do a notification if a process is taking high CPU usage for a while.

Servers have their own solutions like monitoring daemons that sends out an alert if CPU usage had been too high for a while.

Just wait, we’ll soon have an app for that — the equivalent of fake engine sound for EVs.

Haha!!!

Sorry but is this crazy to need the fan to sense the performance!

I like the idea. An app that roars louder the higher the cpu load.

Nullsoft (remember them?) had 'beep' which was always a joy to run.

Of Winamp fame? Of course!

Once I get mine, I plan on building AOSP and seeing what limits I can push the hardware to.

Would you mind sharing the RAM size on iMac Pro? I'm seriously considering buying Mac mini however its max 16GB of RAM is putting me off; fwiw I'm currently on MacBook Pro 2018 (2.6 GHz 6-Core Intel Core i7, 32 GB 2400 MHz DDR4). So any feedback around memory usage/size is very welcome! Thanks!

Nice! Are you using x code as well?

I’m in a similar boat as you - running bunch of node services, pg, etc. but I’m also developing for iOS. Xcode kills my current MacBook because I’m constantly rebuilding.
