I've went through Denial, Anger, Bargaining, and now in an Acceptance stage after taking up to 31% performance hit on some of services managed by my team. Worst case has been Elasticsearch so far with our load pattern, taking that 31% hit.

Oh well, too bad, enjoying the ride.

Can we get a before/after with a new battery vs a battery with 1k, then 10k, cycles on it?

I'm curious what the delta is between perf hit on an iPhone 6 and an iPhone 8. I'm guessing that, given the deadline apple had to get this out, most of the attention & optimization went to current devices versus near-EOL devices like iPhone 6.

Why does Cloudflare tell me I'm able to browse a snapshot while the site is offline, but there is no snapshot?

This might sound dumb but.. with these Meltdown + Spectre bugs would an attacker be able to penetrate to gain full access only if a user downloads a native app or would it be possible through the browser/js?

Time to switch to an Epyc host?

Wow. After ios 10.2.1 halved performance on my iphone 6 due to the battery issues, I next avoided 11.0 as I accepted responsiveness would be slower on the older iphone6 model.

Now if we want these security fixes that's another -40%... Yikes!

However, it looks like ios 11.2.2 and a new battery is still slightly faster than ios 10.3.3 and an old battery! (geekbench single/multi core score from article of 924/1616 vs my 844/1379)
