Serious question—
Does/would a high-end (e.g., Xeon-class) processor and/or a boatload of RAM help keep Code's performance snappy?
FWIW, I run my Code install quite light since my "duties and responsibilities", ahem, only require a few languages/data types, ergo, I am not pushing it hard at all.
FTR, I have a (licensed) install of Sublime, which I confess is snappier than Code, but the difference is so small I use whichever one is better for the task at hand and any difference dissappears under the pressure of an outage enforced deadline :-D
