Re: Green threads in 1.9.* ?

From: rex goxman <lists@...>
Date: 2012-07-04 12:26:32 UTC
List: ruby-talk #397173
If jacques1 is right, then there are no green threads, just kernel 
threads, and I'm out of luck (anyone know why they would do away with 
green threads instead of keeping them and also adding kernel threads?).

I did a quick-and-dirty test here (ruby 1.9.3) to try to shed some 
light.  My assumption is that green threads should be incredibly cheap 
to create (on the order of at least thousands per second), where as 
kernel threads should be much, much slower.

(1..5000).each {Thread.new{}}

This takes around 12 seconds to execute on my machine.  It seems far too 
slow for green threads (I can create hundreds of thousands of green 
processes in erlang per second).  However, someone out there correct me 
if I am wrong, but I would also expect kernel threads to be much slower 
than the above, i.e. on the order of a few per second.  I coded up a TCL 
version of the same above, which I know uses kernel threads.  It only 
spawned a couple heavyweights per second.

I guess the results are indeterminate?  Hopefully someone else will 
chime in who knows definitively.
