Possible, but it would have to be 50-100 users which I am not expecting currently. Seems to handle 5-15 just fine (personal use) smile.gif

I can see through vSphere though that when the machines aren't actively being used RAM usage drops all the way to around 20 MB.

MySQL probably is 90% of that...its very RAM intensive. My VPS is OpenVZ which is the most popular virtulization software from what I can tell...Either way, my system initially used 7MB @ idle (before updates) wink.gif

Thanks for the tip! I will definitely be in both of them in the future then...Do you know if either relies on SQL lite or something standalone like that? Teamspeak would use alot less apart from the fact it has to use a integrated SQL package because I don't use MySQL...

I can understand the VPN for remote access, but wouldn't the encryption mess with Teamspeak?

The VPN is to route my local PC through my VPS, to the internet. The SSH is a seperate thing...I can now access Hulu @ 20mbps and I don't have to rely on oversold VPN providers rolleyes.gif

The server I have is a 4x intel xeon 1.4ghz HT with 4gb of ram. Soon to be upgraded to 4x 2.8ghz xeons, and possibly more ram. But as I said, it is hooked up to a really bad 3mbps connection that has high latency.

Dam, sounds even better than my 1U server I got from work for free lol

But no, I am renting the server from a U.S based company for $1/month (HERE). I didn't even need one but at that price, I couldn't afford NOT to rent one biggrin.gif

Oh, very nice. A bit off topic but are you doing this for every PC in your house or just the one rig? And are you also doing this for all Internet-bound traffic (IE including games and such) or just browser related content? Is there any noticeable lag for any of the applications?

Install something like minbif or bitlbee and you can route MSN, AIM, ICQ and so on via IRC too. Plus if you set up a ZNC, you can idle on those clients (as well as regular IRC networks) and then sync up your away messages when you next log on.

Half my virtual machines run on 256MB or less. It's easily done.

Just my main PC currently, but it could handle multiple machines without issue. For games, even though the connection is faster than any public VPN provider, latency is still too high in comparison to my regular connection. Website (HTTP) traffic works perfectly though...And so would torrents, teamspeak, etc but currently my Ubuntu client only supports transferring HTTP traffic over the VPN connection.

I am now looking into a linux OpenVPN client that is able to transfer ALL internet traffic over the VPN:)

Can't your router do this? Many have VPN clients built in.

The reason the memory usage is so low is because it's container based virtualization. You aren't running your own kernel or drivers. If you're looking for a low end VM like this (low resources, low price), stick with containers like OpenVZ (like the OP has) because trying to run a full OS on such low resources on full virtualization (KVM/HVM for instance) is wasteful -- you'd use up 80% of the memory just with the OS.

I have a 128MB VPS that I bought on a whim from 123systems tongue.gif I paid like $12 for a full year, but I never even use it. If anybody wants to shop for a VPS of their own, I recommend LowEndBox and WebHostingTalk.

Good point, never thought of that and mine probably gcould (Dlink Extreme N). The only thing is I only want to use the VPN occasionally, and only on my PC so I'll be looking for a better local client instead.

No problem! I was actually using it for Hulu yesterday haha...Was getting 20mbps down and 3mbps up through my VPS according to speedtest.net and Hulu wasn't even buffering thumb.gif Not sure why people pay $5-10/month for shared VPN access when they can rent a VPS for the same amount and set one up themselves...And yes, if you configure it right, you can bypass P2P throttling but an easier way of doing it would be a seedbox (which is next on my list). Let the VPS do the torrenting (let it run 24/7) and download from it (HTTP) when complete.

kernel and drivers shouldn't actually take up that much memory.
On my 128MB FreeBSD VM (not a FreeBSD jail), the OS runs snappy and reports that the kernel is only using 2MB. I'm a little rusty with kernel development these days, but if I understand correctly, kernel drivers should be using kernel memory space, thus would be included in the 2MB figure. Obviously the drivers would take up more on a typical system, but on a headless VM you wouldn't expect them to be that large. My 256MB Linux VMs tell a similar story.

Correct me if I'm wrong, but I think the biggest benefit of containers is speed rather than memory footprint. The OSs are running natively - thus there's no emulation layers required.
