Global cache garbage collection options for WPMU

  • Hi,

    I have an issue with a multisite installation with a couple of thousand sites which is configured with Super Cache. The issue is that by default each site has no garbage collection scheduled. Is there a better way of globally enabling cron garbage collection for each site than doing it by hand site by site or hacking the wp_options for each site?

    thanks for any pointers! Andy.

  • You could write a plugin that schedules the garbage collection:

    if ( !wp_next_scheduled( 'wp_cache_gc' ) )
    wp_schedule_single_event( time() + 60, 'wp_cache_gc' );

    Put that somewhere where it will be executed when users login to their dashboard and it will schedule the GC for 60 seconds later on that blog.
