evaluating the upgrade of my pc, I stumbled upon the cpu choice, I've always thought that a new ryzen (5xxx or 3xxx gen) would suit perfectly, but I read this and now I'm puzzled.. has anyone have some personal experience in this?

From this Reddit thread it is pretty clear to me - split your project by multiple modules with as flat hierarchy as possible. On my current project we have 300+ Gradle modules. CI builds are utilizing 20+ threads most of the time.

This is a compile of an open source project with 20 modules

[Arkadii Ivanov]

You can run gradle --scan to check where is the bottleneck

Even ryzen laptops are crazy fast...

[Arkadii Ivanov]

If your modules have serial dependcies A->B->C, you won't get any benefits. Modules should be independent if you want to utilize all cores.

I ran a bunch of benchmarks for the M1 stuff, including against a whole series of cloud server and some physical machines I had

[HankG]

In single core stuff the ThreadRippers I had (Gen2, 2018) were a bit slower than a slightly older i7-6700 (2016). The benchmark may have had an added complication of the i7 being Linux and the ThreadRipper being Windows10 though.

[HankG]

It could also be that the i7 maxed out at 4 GHz while the ThreadRipper maxed out at 3.5 GHz too though, but sacrificing clock speed for core count is part of the design.

@HankG any conclusion from the M1 benchs?

[HankG]

Yup, M1 with native Java JDK is very impressive

[HankG]

I've been doing dev under IntelliJ running in emulation and it is noticeably slower than on my 2018 MBP but it's still fine performance

[HankG]

as soon as IntelliJ supports a native JDK though I'm jumping over to it
