# The settings provided below are ideal for a 4GB-8GB RAM server.
# You can adjust values accordingly for higher or lower spec systems, but generally,

# Use DB diagnostics tools like:
# https://launchpad.net/mysql-tuning-primer or http://blog.mysqltuner.com/download/
# to get more insight on your MySQL DB's resource usage and more...
# Special thanks to Yves Trudeau (Percona) for his valuable help on compiling this setup.

# USE: Place the contents of this configuration inside the main 
# Varnish configuration file, located in: /etc/varnish/default.vcl (root server access required - obviously)


# IMPORTANT: The following setup assumes a 2 minute cache time. You can safely increase
# this to 5 mins for less busier sites or drop it to 1 min or even 30s for high traffic sites.
