Much used memory and many processes: is this normal?


I run slackware 12.1. When i open ksysguard, it says that i've used nearly 700mb of memory and there are 114 processes.

What i've done since the boot:
- Browsing the internet with konqueror
- Started kate
- Installed ogre3d (only "make install", not configure/make)

Why is there in the process list 6 times 'agetty' and 11 times 'kio_http'? There are more doubled (or more) processes in the list.

Is this normal?

Don't worry; it is normal. There is a lot to learn about how unix/linux systems manage memory, processes, etc.

I have 160 processes running on a system with no GUI, and it isn't even working up a sweat.

But why so many of the same processes? Is this neccesary?

Isn't it possible to kill some of the processes permanently?

Each have different reasons. The gettys allow 6 consoles to be running and available. http are web daemons that service web requests. Multiple instances of a network service are common so that there isn't a single bottleneck; each instance handles some of the load. Some web sites have hundreds of httpds. For network file systems (NFS), you can have several hundred nfsd processes.

And in *nix systems, all memory is consumed and used. It is freed *when* the next process requires memory, but not until then. Why put away the sugar, if you're going to have more tea shortly.
