A regular static site shouldn't be a problem on a C2D with 4GB, and it shouldn't be swapping either (unless you're doing more than web hosting on that machine).

A regular static site shouldn't be a problem on a C2D with 4GB, and it shouldn't be swapping either (unless you're doing more than web hosting on that machine). I'm assuming you're literally serving static pages and not running much server-side. Many people host static sites on 1GB SBCs and 1GB/1T VMs with no issues, and you can make do with even less. Update: I tried some tests on my secondary server, which is likely slower than your C2D (AMD G-T48E). I simply ran ApacheBench on the Proxmox Backup Server web interface login page since that's the only web service I have running on it. The two machines were connected over Gigabit LAN and HTTPS was used. This is 1000 requests at a time for a total of 5000 requests. While it was running I was able to make a connection to the login page in my browser as well (it took six seconds to load, but it loaded). I think I did the test properly but let me know if I should try something else; it's been a while since I've done this kind of stuff. ~$ ab -n 5000 -c 1000 https://<PBS server>:8007/ This is ApacheBench, Version 2.3 <$Revision: 1843412 $> ...
