Cloud could cost 50% more. We will bear it.
- MaxBarraclough 8y ago> Cloud could cost 50% more. We will bear it. Likely far less impact than this, as much of the cloud isn't CPU-bound, right?
- smitherfield 8y agoI think that's his point; cloud is often network-bound, which can be orders of magnitude more costly.
- holstvoogd 8y agoGood point. I wonder what the real world impact is, I can imagine all the task switching that happens (at least on my VMs) could have a big impact somehow. Either bad, as in more waiting on memory for instance, or good, as in there wasn't much speculation going on anyway because of it.
- craftyguy 8y agoNone of the fixes have completely eliminated speculative execution, they have only eliminated speculative execution in a few specific cases. Wiping it out across the board would likely have a massive impact on performance.
