I am not referring to the speed of hosts but the SEO weight of RT's templates.
For example, Afterburner blurb saysAfterburner is the fastest Joomla template ever and is completely free. The theme balances speed and search engine optimisation with a full feature set. The template is based on the standard SEO layout used in club templates, and is therefore fully dynamic and collapsible.
It would be nice to know the speed of other templates in relation to each other.
