Web Performance Tuning

Negotiation

If at all possible, avoid content negotiation if you’re really interested in every last ounce of performance. In practice, the benefits of negotiation outweigh the performance penalties. There’s one case where you can speed up the server. Instead of using a wildcard such as:

DirectoryIndex index

use a complete list of options:

DirectoryIndex index.cgi index.pl index.shtml index.html

where you list the most common choice first.
