Darn, I should have made that a premium feature. But… it will be included in the free version for now. You can “pay” by giving a nice review or donation if you want 🙂
Something I’d like to know. The plugin Simple History was recommended to me by ChatGPT. Before, I was using the plugin User Login History for a short while, but that turned out to be a nightmare, because my webhost’s server received so many admin-ajax.php requests (almost every second) that they blocked my IP address, even several times. What load does Simple History cause to a webhost’s server?
Simple History should have a very small effect on your load. It only acts when there is something to do, for example it only writes to the database when WordPress fires a specific event, like a user login or post update.
If you have the dashboard or the simple history log page opened there will be a call to admin-ajax.php (or to the rest api, they work pretty much the same) every 30 seconds. This is to check for new events and notify the user if there are any. But if there are more than 10 events it will stop looking.
