I would be wary of an OS developed and promoted by a hardware
manufacturer (Intel). The Phoronix benchmarks you linked were conducted
on an Intel Xeon chip. I wonder how Clear OS performs with AMD chips,
which are featuring very attractive performance and price recently.

Dear Program devs and enthusiasts,
After seeing James' email (on dismal CPU performance), I was searching
for various ideas and found the so-called "Clear Linux Project". Seems
" function multi-version patch" leads to significant improvements.
Though I could install the precompiled binary of CCP4 and phenix
without any issues but there are no improvements to runtime as FMV
needs 'patching' and compiling.
Could DIALS, CCP4 or Phenix programmers see if this is
useful/possible? Has anyone tried it?

I have a dissenting opinion about computers "moving on a bit". At least
when it comes to most crystallography software.
Back in the late 20th century I defined some benchmarks for common
crystallographic programs with the aim of deciding which hardware to
buy. By about 2003 the champion of my refmac benchmark
(https://bl831.als.lbl.gov/~jamesh/benchmarks/index.html#refmac) was the
new (at the time) AMD "Opteron" at 1.4 GHz. That ran in 74 seconds.
Last year, I bought a rather expensive 4-socket Intel Xeon E7-8870 v3
(turbos to 3.0 GHz), which is the current champion of my XDS benchmark.
The same old refmac benchmark on this new machine, however, runs in 68.6
seconds. Only a smidge faster than that old Opteron (which I threw away
years ago).
