Greetings all. I have seen a couple of diagrams on the net that look like a computer set up as an nginx server and more than one mongrel server running at once. What is the advantage of having more than one mongrel server running? Is there a good how-to that explains it very well. thanks shawn ---

So that you can process more requests in parallel. Fred ---

Fred, Great, thanks for the reply. Do you know what book or site may have a good tutorial about how to pull this off? Most of the docs and tutorials i find just show setting up and nginx server with passenger. Thanks again On Aug 9, 4:02 am, Frederick C.

Right now i am using Nginx with Passenger to deploy. Does this only allow for one instance of Rails to run in each virtual host? I read in the Agile book that Rails is single thread and can only process one request at a time. I guess i need a more parallel approach. Also, and i did not think of this before, but is passenger actually running the rails app like webrick or mongrel ? Thanks for all of your help. shawn ---

Passenger provides that parallelism automatically. Read about it before assuming it won’t work. > Also, and i did not think of this before, but is passenger actually > running the rails app like webrick or mongrel ?

Passenger (with either Nginx or Apache) is usually the simplest and best way to deploy Rails applications. What’s your use case like that you need something different? > Thanks again ## Best, Marnen Laibow-Koser [http://www.marnen.org](http://www.marnen.org) removed\_email\_address@domain.invalid ---
