BENCHMARK no.1                                                                                                                   
==============                                                                                                                   

This benchmark compares spkg with pkgtools and plain tar.

Hardware setup used:

CPU: Athlon Thunderbird 1GHz
MEM: 512MB SDRAM 133MHz     
HDD1: Seagate Baracuda 7200.9 80GB
HDD2: Samsung SP2002H 20GB 7200 rpm
OS: 'vanilla' linux 2.6.17.2, slackware-current

Benchmarking methods:

Before each 'install' benchmark clean ext2 filesystem will be created on
HDD2 using following command:                                           
  mke2fs /dev/hdb                                                       

Before each benchmarks caches will be flushed using:
  echo 2 > /proc/sys/vm/drop_caches                 

All services that could affect result of benchmarks will be stopped.

Install speed
~~~~~~~~~~~~~
Install/extract all official slackware-current (2006-07-11) packages
from the installation packages on HDD1 to the root directory on HDD2.

1)
  spkg -r /data -i */*.tgz

2)
  installpkg -root /data */*.tgz

3) 
  for f in */*.tgz ; do
    tar xf $f -C /data 
  done                 

Remove speed
~~~~~~~~~~~~
Remove all 'kde*' packages from the system. ;-)

1)
  spkg -r /data -d `spkg -r /data -l 'kde*'`

2)
  ROOT=/data removepkg `spkg -r /data -l 'kde*'`
