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
$ time make -j12 # this is a 6 cpu/hyperthreaded to 12
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.
