@ltning I've managed to add more memory since I first installed the system, so it's not quite as tight as it was (and now there's meaningful disk cache, which seems to help loads).
Looking at the stats on it, snac is using 13.5MB (resident), Apache is using 10.5MB.
I think the perception of Apache as a resource hog may have come from the "prefork" MPM there's other, lighter MPMs you can use instead.
Yeah - it's doing TLS in apache. https://social.cobaltqu.be/theothertom/p/1717810603.209255 if you want a sense of how quick it is.
