Ahoj, jakou máte prosputnost sítě ? Já skrz 10MB-FD procpu 1.36Mb/s přičemž přesná konfigurace je taková :

Noťas (10MB-FD) --------- Router cisco(10MB-FD + NAT) --------- Switch cisco(100MB-FD) --------- Switch cisco(100MB-FD) ------- Server(100MB-FD)

Úzký hrdlo je mezi noťasem a routerem, kde je jen 10MB síť, router také zajištuje pro noťase NAT takže to na výkonu nepřidá. Měřeno s netperf. Nevíte jak ještě protoz na 10MB-FD urychlit ? Zkoušel jsem toto http://www.cyberciti.biz/faq/linux-tcp-tuning/ ale bez výsledku.
