My Server has 64Gb of RAM and I am often using Machine Learning applications where I generate lots of data and sometimes run deep networks, etc. That said, my Mac does handle alot of it pretty well.
Another thing is that I tend to run into memory problems on my Mac even just running Firefox and Thunderbird at the same time, especially when Spotlight decides to re-index, so there often isn’t very much left for Julia - in that case, the external server helps alot. I did play with the VSCode remote access feature, which is handy. [I wish there were an easy way to just save everything in Julia between sessions, and that option would be more attractive -the equivalent of ‘save’ in MATLAB - not sure JLD/JLD2 works seamlessly for that]. Anyway, thanks for your comments.
