Most compilers won't fsync will they? The output is likely not being written straight to disk.

It's caches all the way down.

And to max out disk bandwidth before you max out your CPU cores you need a really terrible disk.

I don't think many 8-way Xeon Platinum boxes have eMMC storage.

Well, using ramdisks will let you compare and make sure the disk isn't the bottleneck, at least.

But all compilers will close(). Compare compile times on tmpfs and you will see an improvement.
