Hello all,
I have a PowerPC, 64 RAM, with woody updated. Icewm as Window Manager.
The trouble is: it's so slow, sooo sloooow. It takes 5 seconds to open a
terminal, and so on. XFCE was not bearable. Not to saw about Gnome or
KDE.
The MacOS 9.2 on the same computer is an arrow, compared to it!
Did I forgot to remove some useless processes?
There is a "Small X" howto somewhere on the net I think. It describes
how to save memory in your X setup.
In X:
- Remove font servers
- Remove all scaleable fonts from X font path
- Disable backing-store (X -bs, depends on how you start X where this
must be changed)
- Do not use background graphics only xsetroot -solid <something>

Portmap is only needed if you absolutely want fam (for KDE or Gnome) or
nfs. I don´t think you need any of them.

statd is only for nfs

Do you have a printer? If not stop cupsd.

If X is working, gpm is useless. Do you use a modem? If not remove diald.

inetd is probably not needed - ssh is the only login service you should run.

This must go away. Scaled fonts use a lot of memory in X for some reason.

Have a look in /etc/inittab, you probably don´t need that many gettys,
but on the other hand they´re very small.

Might be usefull to compare the size of gnome-terminal with rxvt. Keep
the number of lines in your scrollback-buffer low.
