Ahoj, mam domaci server se 4 jadrovym Intel Atomem. Sitovky jsou nasledujici:

eth1 - LAN (TP-Link PCIe 1Gbps, Realtek cip)
eth2 - WAN (Integrovana Intel 1Gbps)
eth3 - PtP WiFi spoj do druheho baraku (Cinska ASIX USB 100Mbps, pripojena k UBNT NS)
wlan0 - LAN (Atheros 802.11bgn miniPCIe)

br0 - LAN (eth1 + wlan0)

Internet mi chodi maximalne 30/25Mbps, vetsinou mene. Vsechny jadra vyuziva v prumeru na cca 4,5%.

Vsechno funguje dobre, nejsou zadne problemy. Dnes jsem si vsiml, ze WAN sitovka pripojena k ISP mi ukazuje RX dropped na celkem vysoke hodnote. Vsechny ostatni sitovky maji dropped/errors rx i tx na 0.
