I'm working on a small online learning platform built with WordPress and an LMS plugin. It currently runs on shared hosting, but the number of students is growing, and simultaneous logins and course activity are becoming an issue.

I'm considering moving to a VPS with 4 vCPU, 8 GB RAM, and NVMe storage. The expected budget is around $30 per month.

HostPro.com is among the providers I've been researching. Has anyone run an LMS or a similar application on a VPS with these specifications? I'm especially interested in how much memory is needed when multiple users are active at the same time.
