This is a performance comparison of the the three most useful protocols for networks file shares on Linux with the latest software. I have run sequential and random benchmarks and tests with rsync. The main reason for this post is that i could not find a proper test that includes SSHFS.

The secrets of MTU - L2 MTU vs. L3 MTU - Where does the fragmentation happen?

Source: https://www.packetstreams.net/2018/07/the-secrets-of-mtu-l2-mtu-vs-l3-mtu.html

"The Maximum Transmission Unit (MTU) is the largest possible frame size of a communications Protocol Data Unit (PDU) on an OSI Model Layer 2 data network." In today's network the standard MTU for Layer 3 IP packet is 1500 bytes. Meanwhile, the standard MTU for Layer 2 Ethernet frame is 1514 bytes ( 6 bytes source MAC + 6 bytes destination MAC + 2 bytes EtherType + 1500 bytes IP packet). For the Dot1Q trunk frame, extra 4 bytes for Dot1Q tag is added. So up to here, we understand that there are two types of MTUs. MTU for layer 2 frames and MTU for layer 3 packets.
