The performance hit is absolutely tiny and it doesn't matter for the overwhelming majority of users. It might be that ex. High frequency Trading avoids it, but anything like that is already running an incredibly precisely engineered stack; for 99% of usecases, the performance hit is insignificant.
Are you referring to https://stackoverflow.com/questions/21889053/what-is-the-run... ? If so: I'm hesitant to put too much weight on an answer from 2015, based on running different builds in/out of docker, sitting right under another answer that shows basically no performance difference on anything except network (and with the ability to fix that by using host networking if you care). And even that post doesn't show "100% performance decrease", it shows a 41% drop (184857.06 / 312836.64 = 0.59).
If that's not the SO post you mean, then please point me to the right one.

Stackoverflow answer show 100% performance decrease for a benchmarck with memcached.
