If anyone cares, here's the results of my little experiment.

setup:
- application: authentication (RESTful authentication plugin on Rails
VS auth-core on Merb) and file uploads (attachment_fu on Rails VS
basic file uploads on Merb)
- server running on my machine (2.13GHz Pentium M, 2.0 GB, Ubuntu
Linux)
- clients running on: localhost, 2 other Linux machines, 3 other PC
machines (total 6 clients all running on the local network)
- all clients start approximately at the same time and upload files
(64KB or 1MB) to the server application
- mongrel runs behind Apache with mod_proxy

--average client upload time in seconds--
setup           64KB    1MB
1 mongrel Rails 2.20    3.24
3 mongrel Rails 0.70    1.96
1 mongrel Merb  1.85    2.23
3 mongrel Merb  0.15    0.15
9 mongrel Merb  0.18    0.18
