[SOLVED]Poor network performance

What speed are you getting? How big is the test file you are using?

 

Is the transfer over SMB?

 

Do you have another PC on the network..what speed do you get transferring between those two machines (take the unRaid out if the equation for the testing...)

5 Go

Yes

4 Mb/s but the other pc has a 10/100 card.

See all the link up/down messages? Your nic is definitely not happy. There was also an unhandled interrupt or something causing the nobody cared trace at 13:19. That's either your nic or something that shares IRQ 17 with it. Can we see the output from:

 

 cat /proc/interrupts

 

This doesn't look like a physical link problem but a simple test to get out of the way would be to try another Ethernet cable and another port on the switch/router it's plugged into.

 

What motherboard is this?

Motherboard : Asus P8H67-V

As integrated network adapter is not recognized by unRAID I installed an Intel Pro 1000

 

Thank You for your help

But after some time I again the occurrence of these errors in syslog :

On the console I get the message:

Disabling IRQ #17

As a work-around, it may require to change bios settings, or potentially adding a line to one of the .conf files ???  First it will require to identify which bios option is causing the irq nobody cared fault...

Appears to be a problem with the Asus MB
