This is a question, not a problem. My old Virtualmin server v3.94 running on a Debian 5.0 server with a single core processor and 1 gig of RAM. It was consistently using between 300 - 700 meg of RAM. Even though it was a lightweight it ran pretty much flawlessly. However, from time to time it would start hitting the virtual memory and slow way down.
So, I’ve upgraded it to Virtualmin server v3.94 running on a Debian 6.0 server with a quadcore and 4 gig ram. Right now both servers are sitting side by side running exactly the same websites. (thanks to your supper easy backup and restore process) The new and old server are using:
new 4 gig server: using 780 meg of RAM and 10 meg virtual
old 1 gig server: using 340 meg RAM and 170 meg virtual
My question are why?
Why would the new one be using so much more RAM and 10 meg virtual?
With 3 gig of unused RAM why is the new server swapping anything?
This isn’t a problem, just for my education. Both servers deliver the pages at about the same speed, with maybe a slight advantage to the new one.
