You mention using 512Mb Ram and as a new user of a Pi 3B+ which has 1 Gb Ram 
it does swap
out with a basic install plus web, ftp, ssh services and a not on BBS (back up 
only).

Running a system monitor (Gkrelim) which itself takes up resources load often 
is high at
least when I go in via ssh so I wish you luck.

In other words your proposed system is not up to the task.

Enev with a Pi 3B+ it will strugle at times depending on the direct HDD 
resources you have
set up,
