My house has a similar issue with a lower level that is perpetually much colder than the upper level. The main way we have somewhat alleviated the problem is by opening/closing registers. In the summer, we close all the registers in the lower level, forcing all the cold air from the HVAC into the upper level, then letting it sink down naturally. Our lower level is still cooler, but it isn’t as stark a difference. Due to the layout of the stairs linking the two levels, a fan is not terribly effective at exchanging a lot of air between the two on its own.

This lines up with my experience. I have nextcloud and wordpress on two different vps’s and just checked their ram usage.

• nextcloud: 468 MB
• wordpress: 120 MB

Caveat to the above is that nextcloud is installed bare metal rather than docker and I have both nextcloud and wordpress set up to use object storage as the media back end.

edit: To add to this OP, the reason we are only talking about ram numbers is that the cpu usage for these applications (with primarily only a single user) is pretty much zero most of the time, so you aren’t going to be limited by the single core machine.

Also, depending on your use case (large amount of data on nextcloud or large media files in wordpress), you might run out of disk space pretty quickly. In those cases, you should consider using object storage as your nextcloud or wordpress media backends as it is cheaper than block storage (there are plugins/tutorials to configure object storage and Linode offers it).

My isp doesn’t support ipv6 in my area (Verizon). They claim to be in the process of rolling it out, but it’s been years that they have been saying that, so idk. At least they don’t use CGNAT, so it isn’t a huge deal for me after I set up dynamic DNS.
