Linux and Memory

For anyone interested in the performance benefits gained by adding
memory to Linux.

I have been a Linux user for about the last year and I had been
considering adding more memory to my Linux system but wondered if
the investment would be worth it.  I have always heard that the
best thing to improve Linux performance is memory.  With memory
prices falling lately I made the plunge and upgraded my system from
8 meg to 24 meg.  My system is a IBM clone with a Genoa Turbo
Express 486VLG-X4 motherboard, Intel 486DX4-100 CPU and a Genoa
8500VL-18 video card (Cirrus Logic CL5428 chipset) with 2MB.  Linux
install with this hardware went with _no_ problems.  Anyhow, the
following are some simple performance times for routines performed
before and after the memory upgrade:

free cmd with 8 meg:
          total    used    free    shared    buffers
Mem:       6328    6044     284      3716       2076
-/+ buffers:       3968    2360
Swap:     35244    3852   31392

free cmd with 24 meg:
          total    used    free    shared    buffers
Mem:      22680   16260    6420     12032       9016
-/+                7244   15436
Swap:     35244       0   35244

Times for routines (min:sec):
                                8 meg        24 meg
Boot to X adm login screen:     3:05         1:52
Xlogin until fvwm ready:        1:07          :17
open xterm:                      :10          :03
start admin module:              :07          :03
run short test script:           :16          :04
start xman:                      :14          :05
compile short C program:         :24          :04

These are just some informal times off my "Swiss Watch Clone" only
done to see if the investment was worth the bucks.  Of course your
mileage may vary.  For me it confirms what I've been told, Linux
Loves Memory.  It's kind of spooky not hearing my hard drive banging
away all the time on the swap partition but I suppose I'll get used
to it.   ;-)

Hope this little bit of info may help someone decide if they should
invest in memory or not.

I too recently took advantage of falling memory prices and upgraded
from 8 to 24 meg.

It's true. It makes a world of difference.
