For web serving, Rails has primarily uses FastCGI, which is a multi- 
process model.

43 Things runs our site off of a 2 CPU box with HT enabled, so we get  
4 CPUs.  The multi-process model works great for this, you don't have  
to worry about threads here because of the way Rails is designed.   
You do, however, have to worry about memory.

(It would be nice if you could fork(2) a live Rails process so it  
wasted less memory, but I think you would loose the benefits of  
memory savings the first time the GC runs.  Doug Beaver had a nice  
presentation about this at the last Seattle.rb meeting, where he  
proposed building a separate tree for GC marking...)

But then I need to process the web server's logs, which involves DNS  
lookups.  This is acceptable but not-so-great because I'm using ruby  
threads for that, and that probably chews up more CPU than needed  
switching between the 100 threads.

(For reference, 1 worker thread takes about 5 hours, 20 cuts that to  
3, and 100 cuts that to 40-50 minutes for files in the 750,000 to  
500,000 line range.)

I could rewrite it to be multi-process instead of multi-threading,  
but then the code loses its simplicity.  I could also rewrite it to  
spawn new threads up to N when threads are blocking, but then, again,  
I lose simplicity.

So we run 30 FastCGI processes for web serving and 100 ruby threads  
for DNS lookup, just for reference.
