DSM-G600, DNS-3xx and NSA-220 Hack Forum

I've got very ugly problem:
TX speed 3 times slower then RX on my DNS-323 device
I tested firmware 1.04 kernel and last orion branch(with mv643xx_eth driver)

my results:
RX speed: ~22 MB/s
TX speed: ~7 MB/s

but wiki page (http://dns323.kood.org/information:benchmarks) draws another picture:
RX speed: 20 MB/s
TX speed: 16 MB/s

people who posted those results,
please provide your kernel configs (and kernel versions)
