Ethernet performance on Linux 3.6.0

I have upgraded Linux kernel to 3.6.0 from 3.3.0 on Zedboard.  The network performance degraded badly. 

We found that the network communication jams for about 0.5s randomly. 

 

Does anyone encounter similar problem?

Re: Ethernet performance on Linux 3.6.0

I experience the same thing with the more recent 3.8 kernel. The ethernet connection is pretty slow. But when I test again booting a 3.3 kernel from the sdcard that came with the zedboard it gets at least twice as fast.

 

Does anyone know what is going on here? Should we forever use an old kernel?
