overcome limited RAM on VPS
overcome limited RAM on VPS
Hi,
Do you have suggestions for kernel tweaks for getting the most out of a RAM limited system?
I am running a service requiring 2GB of RAM (netbird) on a VPS which has just 1 GB of memory. I am doing so because I am a stingy bastard and I use only free VPSs for my personal use so I get what I am paying for.
Because of this hardware limit in about 12 hours from service start I begin swapping a bit too much. This would still be manageable but soon the hypervisor gets really pissed and steals up to 90% of the CPU. So the only solution so far is restarting the docker containers every 12 hours (not great, not terrible).
Looking to improve this, Iam now experimenting with ZRAM and swappiness and it seems some benefit can be achieved by using some of the Linux kernel feaures. Is there anything else I should look into?

Wow you're right. You are a stingy bastard.
Never run anything on a free tier if you want to keep it. My legit Oracle account got flagged and deleted for no reason so they're dead to me, and I'll tell anyone who will listen. They're thieving assholes and will snatch away free tier the moment it's convenient for them.
Do you really need netbird? What for?
Spend some money, consider it the cost of education
To tag onto this... for a low end VPS I love Hetzner. No, they aren't the cheapest, but the cheaper options are generally bottom-of-the-barrel unstable garbage or require promotions that expire. Hetzner is stable, professional, and cheap. Great choice for a simple personal VPS.
Netcup is cheaper (as far as I know) and really reliable too. Also based in Germany. I use one of their VPS to host my stuff.
Nice! Love to learn new options.
Can really recommend them. They guarantee the lowest price for VPSs and are very reliable. My company (more than 250 people) uses them to host some stuff too.
I've only had good experiences. Very reliable.
I'm going to chime in and recommend Racknerd. Inexpensive and rock solid for me.
As long as you're not running Plex lol
I use Vultr and OVH.
I've heard good things about OVH.
