I’ve had a 2015 16GB MBPro for the previous few years. It’s presently on Mojave. On it I’ve been working all types of heavy responsibility packages concurrently together with Pycharm, Intellij, RStudio, Spark servers, productiveness apps, and multitudes of browser home windows. It has been a balancing act to get them to coexist and I do have to shut down /restart chrome roughly day by day to clear up its share. However the huge image is: numerous heavy apps are doing properly working on the restricted RAM out there.
Just lately I bought a brand new MBPro with 64GB RAM with Catalina I didn’t count on to have any points given the 4X improve in RAM. To my shock I’m seeing excessive fifties of GB’s of RAM working primarily the identical packages. The one distinction is that I let Chrome run perhaps a few days between restarts. However that is solely accounting for about 10GB of the whole.
After killing the whole lot – as proven beneath – there’s nonetheless 19.5GB of RAM and seven.5GB of swap getting used. The place is that reminiscence going?
Observe we’ve solely the minimal gui apps plus chrome that I restarted solely to carry up this stackoverflow web page.
Have a look at the reminiscence utilization by apps: nothing above even 500MB
I’m not working backend stuff. No servers. No
DropBox however I am a light-weight person of it.
So I’m at a loss the place the reminiscence is getting used. That is in stark distinction to my _MBPro2015/Mojave_ which might be at round 5GB whole underneath the identical circumstances. Any concepts?
