@mattcomi why so much ram?

@mattiem future proof for the next 5-6 months.

@mattcomi ram is so important if you are running virtual machines. When I used to do that, there was never enough…

@mattiem nah my honest answer is just I want to much much much more than I currently have on my M1. Xcode is horribly slow and I’m constantly playing janitor with running apps to free up RAM.

@mattcomi ohh that’s interesting to hear! I’ve been trying to figure out if ram will help with the development experience there.

@mattiem @mattcomi I know someone who is putting DerivedData into a RAM disk and claims that this is a great idea. I think it could be.

@helge @mattcomi this would imply that disk speed is a major bottleneck here, which I find slightly surprising but maybe I should not…

@mattiem @mattcomi The SSDs are *very* fast now, but RAM is still much, much faster.

@helge @mattcomi yes I am aware of this

@mattiem @mattcomi My concern would be that the speed is eaten up by all the FS layers, but who knows. Sole reason I consider a 48+ machine tbh 😬

@mattiem @mattcomi “this would imply that disk speed is a major bottleneck” I think it actually is for Swift targets, they are not multi core constrained but disk plus single core perf.
The only time I see my CPU exercised is when compiling swift-nio-ssl, ie BoringSSL, which sucks all cores available.
