Please, understand that whithout tmpfs and a lot of RAM, the kernel
_won't_ work with the files from the disk but with the files stored in
the _kernel cache_ which IS RAM, too.

This explains why you get this result:

Taking back your last sentence with precise sementic:

                                                          The point is,
/tmpfs cache (RAM)/ or /kernel cache (RAM)/, having portages work on tmpfs doesn't result in
speed improvements.
