The specs of the Win2K machine (Athlon 800 Mhz, 256 MB) are irrelevat
really, I was just using it compare the render speeds of Mozilla on the
two machines.  Debian is installed on the 6x86 (P150, 112MB.)

I will try some slimmer window managers.  I know these programs need a
lot of RAM but with Gnome+Sawfish+Mozilla loaded, I still have 15-20MB
free RAM (accoring to 'top') so the memory footprint is not really the
issue.  The problem is that simple things like moving/resizing a window,
drawing a menu, or repainting the background can be very slow.  I was
hoping that somewhere I didn't have a PCI bus or video acceration option
set right.

Does anyone know how much the FPU is used by these tasks?  The 6x86 fpu
sucks balls, but I can't really see it being used for web surfing, etc.

Final question: does anyone know anything about the i430HX and its cache
and tag ram?  I have a 256KB pipeline-burst L2 cache module installed. 
I seem to recall that the stock board only included enough static tag
ram to cache the first 64MB.  I bought and installed a 32k x 8 x 15ns
SRAM chip and installed it in the empty socket on the board.  The bios
has an option to set the cacheable ram to 64MB or 512MB.  I cannot boot
with it set to 512MB, I suspect that perhaps the 512KB L2 cache module
might be required (they stopped making these many years ago I'm sure.) 
This all happened a long time ago so I can't really remember the
details.  

Anyway, regarless of this cache business, w95 "felt" a whole lot faster
than woody, so I'm looking for stuff that I haven't turned on or
optimized correctly.

I include below the dmesg kernel startup, in case anyone spots anything
out of the ordinary.

Re: Performance tuning?

2002-06-08 Thread Ron Johnson
Is this an 6x86 P150 or an 800MHz Athlon?  Or is the win2k
box the 800MHz Athlon?

Some musings: 
- how much RAM on the win2k box?  
- On my 1GHz Athlon, I see X spiking up to 60% CPU at times.  
  (Yes, I run X4.1, Gnome 1.2 and mozilla 1.0rc3.  
- Do you run gnome 1.2 or 1.4?
- mozilla is pretty slow to load on my win2k box that only
  has 128MB RAM.
- On such an old machine, best to use a light weight window
  manager instead of a big, fat windowing environment (and
  gnome is much slimmer than KDE!)  Try fvwm2, blackbox,
  or xfce.

I have moved to a different Window Manager on the slower systems/faster 
response demands because I didn't want to wait for anything. 
WindowMaker is available under Debian and, while it's not a Desktop 
like KDE/Gnome, it does do a very nice (and fast) job...
