Slow queries and performance issues

I get the following performance issue on every page request in admin and frontend:

Slow Database Queries (above 0.05s)
Query	Caller	Component	Affected Rows	Time
UPDATE <code>myprefix_options</code>
SET <code>option_value</code> = '0'
WHERE <code>option_name</code> = 'wordpress-https_ssl_host_diff'	update_option()+	Plugin: wordpress-https	0	0.0885

Why is the plugin updating ‘wordpress-https_ssl_host_diff‘ on every page request?
