--- Comment #40 from Marko Cupać <marko.cu...@mimar.rs> --- Hi, I just got advice to try and disable LRO on em0 interface with base driver, and it resulted in acceptable performance in my VirtualBox VMs with bridged networking. I noticed different options between the two drivers: if_em: options=81249b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,LRO,WOL_MAGIC,VLAN_HWFILTER> if_em_updated: options=4219b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4,WOL_MAGIC,VLAN_HWTSO> The difference is that if_em_updated has TSO4 and not LRO, also VLAN_HWTSO and not VLAN_HWFILTER I am back to if_em_updated for now, but hopefully this information will be helpful in fixing if_em.
