There is an opinion that threads and processes are almost the same from

This is from April 2009 - more than 6.5 years old. It talks of Linux 2.4
vs. 2.6. We now have Linux 4.2; don't take this link too serious without
checking if it is still valid for recent kernels.
The most valuable answer was last edited in 2012 with the comments from
2014.
So I would assume that it is still valid even for 4.3.
Are you aware of any significant changes in this field ?
Not particularly. I know that in 2.6 were big chances in the scheduling.
First the O(1) scheduler, later the CFQ scheduler. And the scheduler can
have significant influence on process and thread performance.
