The other percentages we've been offered have been in terms of performance reduction. We were told to expect a range of 5-30%; this is about 60%.
Somewhere a sysadmin's hair has started smoldering.
It really only affects workloads where high performance is important. The average user might not see an impact but if you need fast IO God help you. The solution is to 'make less syscalls' but the problem is that syscalls have always been slow and the people making a lot of them are only doing so because they absolutely have to
You're right. Most people who just surf the Netflix and download the YouTubes will not notice. But it's still a form of fraud, even to those who never max out CPU. I think fraud is a strong word knowing that this wasn't intentional. But they sold a lesser product than they advertised and need to make customers whole. Otherwise it pretty much is fraud.
Do you think browser vendors have been pushing JIT research forward, investing in webasm, and building things like servo because websites are so fast and light on CPU?
If anything, for big shops like this one, I wouldn't be surprised if we saw a move away from hosted providers (the "cloud" .. god I still hate it when people use that word), and return to co-located setups.
At least for people who need immediately performance needs, AMD might make a lot of short term sales right now.
We write a lot of code that needs to run as fast as possible (processing, post-processing, generating real-time weather/satellite data) and I’m concerned about time windows and whether we’ll be able to meet requirements.
You'll probably see a wide variety of benchmark results anything from no impact to things like above. So just make sure you measure carefully with your own workload.
