Is it normal for server with plesk to use 400MB memory wit no clients ?

[adrianTNT]

Hello, I have a dedicated server installed and my plesk statistics says that memory is used 40%, about 400MB (of 1000MB total).

Memory ....... 1008.45 MB
UsageTotal ... 428.57 MB
Used Free .... 579.88 MB
Shared ....... 0 B
Buffer ....... 108.03 MB
Cached ....... 166.70 MB
Usage ........ 42.5%

HDD usage ...... ~550MB
Swap usage...... 0 B (of 1.90GB)

Is this normal for system to work or something uses too much memory?
I have no visitors to sites yet, I have 10 sites uploaded.

Thank you in advance.

A large portion of that memory is used for caching, 166MB.

Your memory usage is normal, all your services are already running.

Uploading sites doesn't increase the server memory usage very much.

So server is ok, right ?
Thank you very much.
I thought server has some problems, I am very new to plesk and dedicated servers.

 

[dsmarty]

Yes, your server is ok!

I've got a gig of memory and its only got 16mb free, is that normal? Im only running 4 active domains on the server, Im sure it didnt used to be that high when I first set things up. There is 341 cached.
TIA

Do you have any further services running on the same server?
Try to use 'top' command to check which process takes most of the memory.

From what I have seen so far it uses more ram as you upload more content, it probably tryes to cache all content in the site?

So with 1GB RAM and 1GB site it will use all 1GB of ram if all content on the site is accessed often by visitors?! Something like that I think.

Its not using any of the swap file so i guess it is just making use of free ram to speed things up? We have one site that is very busy (forum using mysql) and a couple of other databases that collect data from 3 very busy games servers so I guess it is a little busy but the CPU load is minimal.
