Our host provider (Network Solutions) has been providing suggestions as to how to speed up the site without the plugin. Nothing has worked.
I have notied that regular html pages are fine.
And also the phpadmin application that is used to browse/maintain the underlying MySql database also runs extremely fast. Phpadmin is written in php and accesses the MySQL database… WordPress does exactly the same thing phpmyadmin is fast. WordPress is slow.
There must therefore be some setting (perhaps a maximum limit to used memory?) that is affgecting the wordpress blog and which is not set so low for phpadmin. Does anyone know if this sounds reasonable as an explanation? If so then it could form the basis of a request to Network Solutions to get them to do something that would make things better.
