 Hi,

 We recently had a performance issue with one of our websites.
 It works with a custom made theme.
 The frontend and backend were very slow, and sometimes led to 503 errors.

 We contacted our server supplier (cyon.ch) which told us:

 "There are some very heavy load scripts, specially if you upload pictures.
 That causes the following loop:
 SELECT option_value FROM wp_options WHERE option_name =
 'can_compress_scripts' LIMIT 1
 SELECT option_value FROM wp_options WHERE option_name =
 'can_compress_scripts' LIMIT 1
 SELECT option_value FROM wp_options WHERE option_name =
 'wp_installer_settings' LIMIT 1
 SELECT option_value FROM wp_options WHERE option_name =
 'can_compress_scripts'"

 which seems to be a WP core query.
 It is better after deactivating some plugins, but the problems is
 remaining.

 Thank you for checking.
