Rails - Sep 2006 - Does mongrel_cluster support the concept of min-procs and max-procs like lighttpd fcgi where under load additional procs will be created

Does mongrel_cluster support the concept of min-procs and max-procs
like lighttpd fcgi where under load additional procs will be created?

I always thought that was a nice feature, to be able to have a minimal
number of procs running for a site and then when the load increased
fire up additional ones (up to a maximum) and then over time kill
those off when load backs off.

This allows one to host many sites on a server each only taking up a
minimal amount of resources until they are needed. It allows the
number of procs serving to be directly tied to how much load is
actually being used rather than an arbitrary guess.

So thus my question does mongrel_cluster support anything like this,
if so how is it configured (I didn''t see anything in online docs)? If
not, does anyone know if Zed is planning to add anything like this?

Thanks,

Jeff

as far as im aware it doesnt support any of this, when you launch the 
cluster your teling it that you want X instances. By doing this i 
suppose it presumes you have done all the relevant speed and performance 
testing (you have done performance test havent you?!) which should 
enable you to know how many mongrels you can yeild the best performance 
with.

Its not easy, and it isnt a quick solution, but its worth it. If you 
know the optimal setup you just set it to that, safe in the knowledge 
that your application can take XYZ req/s over X servers in Y period.

The bottom line.... you gotta work out your optiomal config and run with 
it for a while, if its stretched you wil need to re-evaluate the load.

Cheers

Tim
