Q: Upgrade dual CPU to faster single CPU

Aug 6, 2016 6:53 PMby Grant Bennet-Alder,If you ask the original drive to make 10,000 transfers, in Reading and Writing Source and Destination files while temporary files are also in use, while the system brings in required pages from the Application and memory is tight so that some items need to be paged out while others are being paged in, your Mac will be slow. But it is not due to lack of compute power -- It is I/O bound. The disk cannot read and write fast enough, and everything backs up. It can appear that one process on one CPU is holding things up, but in reality is is the inability to read and write data to too few drives that is the problem. I/O (Input & Output) Bound.

DesktopsWhy don't you just upgrade both? They are not the state of the art chips anymore and have gotten fairly affordable.

OWC will do the upgrade, but then they swap out the board and if I ever DID want to add a second chip, I'd be paying for that whole service again, which just makes upgrading old tech that much more expensive. And the OWC route is rather cost ineffective overall anyways. Just for the upgrade to a single chip and board would cost 1300, which to me is utterly crazy.
