A number of the Clear Linux optimizations over the years have been upstreamed into the Linux kernel and other software components where relevant, but still there is more work to be done on the part of Linux distribution vendors. At least in recent months we've seen more Linux distributions considering optional or mandated x86_64-v2/v3 support or making other use of the x86_64 micro-architecture feature levels.
