Well, there is a lot to be said about moving what used to be external to internal. It does result in faster moves for pretty much everything. Moving data from one side of a chip to another is faster than moving data out of a chip and then back in again. I bet there is millions of transistors on a CPU chip nowadays. I need to google that Threadripper CPU. 64 cores in the top model I think. I bet it has a ton of transistors in it. > > > > > Thanks for the info.

Sometimes things come up that are more Linuxy than Gentooy. LOL I might add, I've read info on Ubuntu and other distros that solved issues on my Gentoo rig. Less so with the systemd switch now but still happens on occasion. Dale :-) :-)
