WG: Wichtig! Netzwerkproblem sehr sehr langsamer link



 

Hallo,

ich hoffe hier kann mir jemand helfen!

 

Ich habe auf folgenden System Xensource installiert:

 

Athlon x2 4400+ (2x2,3ghz)

2gb ddr 800ram

WD RE 160gb sata

Nic 3com 905

 

 

Die Netzwerkverbindung zum Hypervisor ist so was von langsam…

 

Testdownload per http von einem anderen Server hier im Netzwerk:

17:36:17 (510 KB/s)

 

Über SSH gehen auch nur maximal 800KB/s!!

 

 

hdparm -t /dev/sda

 

/dev/sda:

 Timing buffered disk reads:  174 MB in  3.02 seconds =  57.62 MB/sec

Liegt das am Mainboard oder am Chipsatz?

 

Ich hoffe mir kann jemand helfen
