SRE here, Containers are not causing any performance problem.

Maybe the perception comes from all the Mac and Windows devs having to run a Linux VM to use containers.

Containers themselves don't, but a lot of the ecosystem structures around them do. Like having reverse proxies (or even just piles of ethernet bridges) in front of everything.

Or if you go ping pong across containers to handle a single request. That will certainly make a laptop unable to handle this load.
