Server Memory
« on: January 06, 2006, 01:42:37 PM »
Hello,

I use dedicated plan #1 with 512MB of RAM. I'm not very experienced with Linux administration so I want to ask is this a normal memory usage for this kind of configuration with Apache/MySQL running? Sites are working perfectly and CPU is usually idle 90% or more, but I'm curious is it normal to have only 32MB of RAM free?


free -m

             total       used       free     shared    buffers     cached
Mem:           492        459         32          0         78        231
-/+ buffers/cache:        149        342
Swap:         1019         26        993

That's normal. It doesn't make sense to leave vast areas of memory unused so it is used for the disk cache. The memory listed as 'cached' in your post is effectively free, it can be cleared quickly if required. As you can see, your swap is barely being used so you don't have a memory shortage problem.

Thanks,
I was thinking in the same direction, but I wanted to be sure about that.  :yey:

How much will it cost if additional RAM is needed on plan #1, say per 512MB?

Thanks
If there is a problem, there gotta be a solution.
