I'd like to know where you can get a better performing OS. The file systems
scream when compared to Windows or MacOS, they know about SSDs and do the
right thing. The processes are light weight, I regularly do "make -j"
which on my machines just spawns as many processs as needed.
$ time make -j
real 0m17.336s
user 1m7.652s
sys 0m5.116s
$ time make -j12 # this is a 6 cpu/hyperthreaded to 12
real 0m16.473s
user 1m5.856s
sys 0m4.736s
So if I size it to the number of CPUs it is slightly faster. On the other
hand, when I tell it just spawn as many as it wants it peaks at about 267
processes running in parallel.
Solaris, AIX, IRIX, HP-UX, MacOS would all thrash like crazy under that
load, their context switch times are crappy.

Linux is to diversified at this point to make it
to the desktop any time soon.
I haven't had a job that didn't provide a Linux workstation since the
early 2000s. Linux has made it to the desktop already, regardless of what
goes on in discount electronics stores. It's not particularly good at
the desktop, but then, it's not particularly good at anything else,
either.
