I'm not too savvy yet and have little experience with running a server. So I have a question about RAM and memory usage in general:
Many of the Cloudron apps specify how much memory they need. For example:
- Wordpress: minimum 256 Mb
- Nextcloud: minimum 600 Mb
- Collabora: minimum 1 Gb
- LanguageTool: a whopping minimum of 3.5 Gb
...do the apps need this much memory all the time, only when they are under load or does it depend on individual parameters per app?
I ask because I have some apps installed that have quite high demand - and when I add it all up, my server has less memory than "minimum" required. Do I need to upgrade?
do the apps need this much memory all the time
Yes, at least.
I find that in practice in use they nearly always use more.
It's probably overkill, but I tend to default to manually setting the RAM to double the minimum.
Do I need to upgrade?
More RAM is always good.
But you don't really need more until you start regularly getting apps crashing because they ran out of memory.
