Recommended # of mongrels for a default EC2 node

Rails Deployment

Hi -

I was wondering if anyone had any experience with mongrels on EC2. If
so, how many mongrels are recommended for the default ($0.10/hour) EC2
node?

Thanks!

Generally you want 3-6 mongrels per cpu core. The small ec2 instance
has just one core so I woudl recommend starting with say 4 or 5 and
going up to 8 at the very max. If you saturate your cpu with too many
mongrels even if you have spare ram you will still get worse
performance.
