The Mighty-Mite is our best server option when it comes to its low
power profile. At idle, it uses less power than a 25 watt light
bulb! The Mighty-Mite will handle most apache/php applications with
as many as 1-2 users and still maintain an excellent response time.
Additionally, it can handle email server duties for greater than
20 users including IMAP with TLS encrypted connections.
The Mighty-Mite is an excellent choice for an always on server that
handles email, light web serving, network firewall and routing
duties. The lopoco.com
web server is a mighty-mite, so you can judge for yourself!
