LVE is an acronym, 'Lightweight Virtual Environment'. It refers to how much of a server's resources are allocated to each customer.
LVE limits in cPanel are a side effect of the technology being limited to single-server hosting. Without set limits, one user could consume all the available resources - CPU and RAM - and slow down other websites hosted on the same server.
Because we are not limited by cPanel or CloudLinux, we host our customers across our entire platform through our autoscaling cloud hosting technology. This means we don't have to put any limits on your site's available resources.
