Dotaz: Kolik vyždímete ze svojí sítě ?

[ja_kral_ll]

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.

1.36 Mb/s mi na desetimegabit připadá dost slušná hodnota, dokonce je to víc, než teoretické maximum. :-) Problém bude nejspíš v tom, že si pletete MB a Mb.

[mimi.vx]

snad 1,36 MB ... ze , coz je na 10Mb sit dost .... celkem velmi dost ...

Jinak doma pres FTTH procpu max kolem 28Mb ... coz mi dela neco pres 3MB/sec

[Michal Kubeček]

Omlouvám se, sám jsem se v tom nakonec zamotal. :-( Mělo to samozřejmě být 1.36 MB/s (jak uvádí tazatel), akorát když jsem to psal, myšlenkami už jsem byl na konci té věty.
