One thing to quickly try is to tune the packet capture on
Linux, as the defaults are pretty bad.
See:
http://www.net.t-labs.tu-berlin.de/research/hppc/
For the definitive guide.
The shortcut version is, as root:
echo 33554432 > /proc/sys/net/core/rmem_default
echo 33554432 > /proc/sys/net/core/rmem_max
echo 10000 > /proc/sys/net/core/netdev_max_backlog
which will temporarily increase the size of the packte capture
buffers to 32 MB, and see if that makes a difference.
