If you're not using Linux (presumably you're using MacOS), your "containers" are actually VMs so it's unsurprising that the performance suffers somewhat (not to mention that file accesses are especially slow with the Docker-on-Linux setup). The performance impact of being inside a container on Linux is as close to zero as you can get.
