[VLAN] Performance issue

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi everyone,

My never-ending stream of bumps in the road to success continues..
Everything is working like it should now, with DHCP.

Now it's just a performance issue.
When downloading from the internet I constantly get 10Mbit/sec.

 *  Client 
-> (100Mbit)cisco vlan (same speed on both vlan's)
-> (100Mbit)trunk linux eth1 
-> (10mbit)eth0 with nat to internet


But between the vlans I only get aprox. 2Mbit.

  * Client
-> (100Mbit) Cisco vlan 5
-> (100Mbit) Trunk to linux box and back on vlan 52
-> (100Mbit) Ftp-server

Cant find any errors logged, no load on the system, 
just a transfer rate that jumps between 80 and 240 Kbytes/sec.

Driver(3c59x) is patched, running kernel 2.6.8.1(tried 2.4.27 as well)
No iptables rules are active except for NAT.

Any ideas?

Thanks in advance,
Magnus Ternstr?m
