I mean that after the latest update, the site’s wp-admin was extremely sluggish to the point that it was impossible to get any work done, and the site itself would give an “error establishing a database connection” message a few times a day. I checked the settings, it was not set to recalculate the stats on every run. When I checked the processes on the site’s server, there were hundreds of apache2 processes there, when normally there should be 15-20 of them. Upon deactivating the plugin, the site’s speed returned to normal, and the number of apache2 processes returned to normal.
