Multisite with 220+ sites painfully slow

    We’re having issues with the site being painfully slow. It can take anywhere from 6 second to 20 seconds to login.

    The odd thing is that this only seems to happen with the the Super User account that has access to all 220+ sites, but Super User accounts that only are on a couple sites don’t take as long.

    Any ideas as to why or what’s being loaded in the background? I’m assuming there’s some sort of login hook for that is loading options or preferences that has to do with every site that Super User is attached to.

    I’m thinking maybe if I can disable pre_get_blogs_of_user & update_meta_cache or something.

    The database query that returns from update_meta_cache is 950+ records long and appears to be a user settings for every site it’s a member of. Considering it’s the Super User account, it loads them all.
