正如leung所言，改了之后速度能达到10M/s以上，因为笔记本是百兆网卡。
tx_delay和rx_delay是什么意思？发送延时，接收延时？ 坑货，笔记本的正常了，台式的却更慢了，一百多k/s。
台式网卡型号是Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 0c)
笔记本如果没记错应该是rtl8169.
为什么会这样？:dizzy:都是直接网线相连，没有经过路由器。 本帖最后由 woody.lee 于 2016-3-30 17:45 编辑
這是修改成 0x16的實測數據
接線單純
Server <-> GigaSwitch <-> RK3288
Intel(R) Xeon(R) CPU E3-1220 V2 @ 3.10GHz Chip: BroadCom Firefly RK3288
測第一次跟測第二次有明顯的差異
我是用雙系統,
估計問題是在這
測第一次的時候只更新 resource.img-> Resource
測第二次的時候有更新 boot.img -> Recovery
另外, 如果用 windows 做 iperf的驗證
-r, --tradeoff Do a bidirectional test individually
有加 -r 可以得到

沒加 -r 得到的數據很差:

懷疑是 M$系統有做頻寬保留的動作.
