Pow vs LiteSpeed: What are the differences?
Developers describe Pow as "Zero-configuration Rack server for Mac OS X". Pow is a zero-configuration Rack server for Mac OS X. It makes developing Rails and Rack applications as frictionless as possible. You can install it in ten seconds and have your first app up and running in under a minute. No mucking around with /etc/hosts, no compiling Apache modules, no editing configuration files or installing preference panes. And running multiple apps with multiple versions of Ruby is trivial. On the other hand, LiteSpeed is detailed as "*A drop-in Apache replacement and the leading high-performance, high-scalability server *". It is a drop-in Apache replacement and the leading high-performance, high-scalability server. You can replace your existing Apache server with it without changing your configuration or operating system details. As a drop-in replacement, it allows you to quickly eliminate Apache bottlenecks in 15 minutes with zero downtime.
Pow and LiteSpeed can be primarily classified as "Web Servers" tools.
