Huge number of MySQL requests… ?

Hi folks,

A site im running is showing around 1400 requests per page/post. This being high is a concern, but it is not obviously affecting the site perfomance.

However, there are a huge number of queries being passed in thei form;

SELECT autoload FROM wp_options WHERE option_name = ‘_transient_timeout_dwls_index_51’

And they increment from 0 right up to the hundreds, including alphanumeric hexidecimals ;

SELECT autoload FROM wp_options WHERE option_name = ‘_transient_dwls_index_ff’

Im gonna have a wild guess that its a plugin issue… anyone seen this before ?
