[Mongrel] problems with Mongrel + Pound

 Zed, Emobius,

Thank you for the replies.

Here's what I found - mysql gem was not installed and that maybe a core source of problems as suggested by Zed. We've had? too many problems when we tried to install this, and found that none of the solutions that are mentioned really work. We will try to install this gem again. 

An application that we built using DRB designed to be asynchronous failed to process asynchronous requests, had each instance of ruby piling up request queues and subsequently throwing errors (as all ports were getting requests continuously).

I will be keen to get inputs from anyone who has used DRB instead of AP4R for asynchronous requests

 Ruby version is 1.8.6 (we're upgrading this today night)

Ngnix - we're trying this out today on our staging machines and after it is found to be stable, we will move to production.

Temporarily, we've moved from DRB to AP4R for asynchronous processing. Personally, I am still comfortable with DRB than AP4R but that is another discussion altogether.


Another question: Are there benchmarked transaction statistics on standard hardware for ROR / mongrel platform (similar to whats available on TPC.org?). We're looking at benchmarking our system to initially support 10m requests per day (consider each one to be a simple find_by_sql query against a database of 1000 requests + 1 asynchronous process for billing.

Thanks for that tip -- I checked my Ruby installation and found it  
was that very same buggy version.  I hadn't realised it was flawed....
