Memory-waste in Ubuntu/Debian?
I have 512 mem on this laptop, though 'top' tells me I only have 380. However, Ubuntu is using 288 mb of memory, when I only have 3 terminals, running lynx, vim(for this file) and (of course) top. Considering it I have lynx running a 600 page txt file, which of course would eat some memory but 300? And even worse when i start X. Let's try it. First I reboot since she's been up a couple of hours.

Before X is launched:

Mem: 385812k total, 178516k used, 207296k free, 8700k buffered

Staring at the buffered memory for one minute it's now increased to 8852.
Used mem has also increased to 178888. 300 k on two lines.
(That's probably the two most expensive ascii-lines I've ever seen.)

After X is launched: (mem already at: used: 179260 and buff: 9388)

Mem: 385812k total, 264612k used, 121200k free, 13604k buffered
That's about 80 meg. Starting timer.
13:12:30 (with the above memory)

13:17:30 (five minutes later)
Mem: 385812k total, 265356k used, 120456k free, 14144k buffered

That's another 5 meg memory used. For just staring at the 'top' program.
In two hours I'll run out of memory! What's happening behind the scenes?

Before i rebooted I checked my free memory after starting X.
It went down to 35 meg. It'd been up for 3-3.5 hours running a 600+ page txt file in lynx.

Regards
Richard

(Mem is now (13:27:00) used: 266852 free: 118960 buff: 15220
A lot less in ten minutes than in five... Hmmm...)

LEARN ABOUT DEBIAN

ubuntu-dev-tools

ubuntu-dev-tools(5)						File Formats Manual					       ubuntu-dev-tools(5)

NAME

       ubuntu-dev-tools - Configuration for the ubuntu-dev-tools package.

DESCRIPTION

       The  ubuntu-dev-tools  package  is  similar in scope to the devscripts(1) package, providing a collection of scripts which may be of use to
       Ubuntu and Debian developers or others wishing to build Debian packages.

       Some of these scripts have options which may be configured  on  a  system-wide  and  per-user  basis.   These  options  are  configured	in
       devscripts.conf(5).

       All variables are described in the script's manpages. Package-wide variables begin with "UBUNTUTOOLS" and are listed below.

       Every script which reads the configuration files can be forced to ignore them by using the --no-conf command-line option.

ENVIRONMENT

       All ubuntu-dev-tools configuration variables can be set (and overridden) by setting them in the environment (unlike devscripts).

       In addition, several scripts use the following environment variables:

       UBUMAIL
	      Overrides  DEBEMAIL  and	DEBFULLNAME  when  the	target	is  clearly  Ubuntu.   Can  either  contain an e-mail address or Full Name
	      <email@example.org>.

       DEBEMAIL, DEBFULLNAME
	      As in devscripts(1).

PACKAGE-WIDE VARIABLES
       The currently recognised package-wide variables are:

       UBUNTUTOOLS_BUILDER
	      This specifies the preferred test-builder, one of pbuilder (default), sbuild, pbuilder-dist.

       UBUNTUTOOLS_DEBIAN_MIRROR
	      The preferred Debian archive mirror.  Should be of the form http://ftp.debian.org/debian (no trailing slash).  If not specified, the
	      master will be used.

       UBUNTUTOOLS_DEBSEC_MIRROR
	      The  preferred Debian security archive mirror.  Should be of the form http://security.debian.org (no trailing slash).  If not speci-
	      fied, the master will be used.

       UBUNTUTOOLS_UBUNTU_MIRROR
	      The preferred Ubuntu archive mirror.  Should be of the form http://archive.ubuntu.com/ubuntu (no trailing slash).  If not specified,
	      the master will be used.

       UBUNTUTOOLS_UBUNTU_PORTS_MIRROR
	      The preferred Ubuntu archive mirror.  Should be of the form http://ports.ubuntu.com (no trailing slash).	If not specified, the mas-
	      ter will be used.

       UBUNTUTOOLS_LPINSTANCE
	      The launchpad instance to communicate with. e.g. production (default) or staging.

       UBUNTUTOOLS_MIRROR_FALLBACK
	      Whether or not to fall-back to the master archive mirror.  This is usually the desired behaviour, as mirrors can	lag  the  masters.
	      If on a private network with only a local mirror, you may want to set this to no.  One of yes (default) or no.

       UBUNTUTOOLS_UPDATE_BUILDER
	      Whether or not to update the test-builder before each test build.  One of yes or no (default).

       UBUNTUTOOLS_WORKDIR
	      The directory to use for preparing source packages etc.  When unset, defaults to a directory in /tmp/ named after the script.
