Kis magyarazat:
---------------

A teszt ab-vel keszult (apache bench), a szerveren apache futott, 30-as
keepalive limittel.

a vas: gigabit ethernet kartyakkal (1500-as MTU)

kliens: 900Mhz Celeron, 256MB RAM, 32 bit PCI
tuzfal: Intel alaplap, 2x PIII 1.26Ghz server proci, 512MB RAM, 64bit PCI
szerver: Compaq Proliant DL380 (1x PIII 1Ghz), 512MB RAM, 64bit PCI

A filenevek igy epulnek fel:
ab-         konstans
-k          ha van, akkor az ab hasznal HTTP keep-alive-t
smallfile   10k-s file
mediumfile  100k-s file
bigfile     1M-s file
-<szam>     a szam egy portszam 3 lehetseges ertekkel:

		80: Zorp HTTP proxy
		81: Zorp Plug proxy
		82: forwarding, conntrack-el

Az eredmenyeken tisztan latszik, hogy a proxy tuzfal session inditasa eleg
draga, de ha egyszer mar megy (foleg a keepalive-s eredmenyeknel), akkor
eleg jol felveszi a versenyt a csomagszurokkel is. A session inditas
netfilternek is eleg draga, ez latszik a nem keepalive-os teszten.

A Zorp legjobb eredmenye: 58070 kByte/sec (plug), ami majdnem 600MBit !!!
Ugyanez a teszt HTTP proxy eseten alig valamivel alacsonyabb 57123 kB/sec

A legrealisabb terhelest webszerver elott az ab-k-smallfile jelenti
(keepalive, 10k-s filemeret) itt is kb 160MBit-et kepes atvinni teljes
protokoll elemzessel.

Masodik processzor eseten meg van mit javitanunk (a Zorp-on illetve a
kernelen) Magas lock contention eseten ugyanis erosen romlik a teljesitmeny.
