No, Logtivity won’t impact the speed of your sites.
We store each active log asynchronously. This means that WordPress can carry on processing the request straight away and does not have to wait for Logtivity. Your site does not slow down for our plugin to contact Logtivity.io and record new activity logs and errors.
Also, Logtivity limits the reasons we contact our central dashboard. For example, we only check once per hour for any new settings that might have been added in the Logtivity dashboard.
