Have not had this experience. I find Macs to be faster in fact as the SSDs are normally much faster than most linux machines.

This isn't about SSD speed. Reading large file is comparable, but there is a very large overhead on the initial file access because of sandboxing.

Opening (or deleting) an empty file is about 2.5x slower on OSX than on a Linux running in VirtualBox on that same Mac: https://discuss.rubyonrails.org/t/why-is-rails-boot-so-slow-...
