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. -- Bazsi PGP info: KeyID 9AF8D0A9 Fingerprint CD27 CFB0 802C 0944 9CFD 804E C82C 8EB1
