Good afternoon, I recently installed Debian Wheezy (7.0) on a freescale board (SABRE MCIMX6Q / iMX6Q) and discovered some disturbing lags for all network communications.
What I have tried so far was to set the network configuration in /etc/network/interfaces to static values instead of DHCP and I checked the OS load as well:
13:20:51 up 31 min, 2 users, load average: 4.75, 4.67, 3.89
The top command may consume up to 15% CPU which seems very high as well. For the OS installation we used a pre-built u-boot.bin, uImage and a Wheezy RootFS (Hard-Float).
Kernel which was compiled for wrong hardware by any chance?
Whereas other network members have low response times, this one lags even when pinging a machine on the same network, here is a short excerpt of the output of a ping command:
And below is the board, perhaps it's a specific problem.
