Sometimes the wp_options table can get really big and bloated. This could be related to poorly written WP plugins or either tons of _transient entries left in the database. Transient entries are usually created to simply store cached information.
This is solved with such sql:
DELETE FROM `wp_options` WHERE `option_name` LIKE ('_transient_%');
Or check the number of not needed records with such sql:
SELECT * FROM `wp_options` WHERE `option_name` LIKE ('_transient_%');
