Solved how to use 1GB/s network transfer data in freebsd14.1

[fff2024g]

Dear all :
i have 5 Gigabit Ports in my switch . double freebsd14.1 hosts plug in this switch. why transfer data use scp command only 100MB/s ? the speed must be 1Gb/s .
any one can help enable 1GB/s transfer speed ? thanks.

Your are maxing your Gigabit with 110 MBytes/s

The above answer is correct.

Convert MiB to megabit - Conversion of Measurement Units

Do a quick conversion: 1 mebibytes = 8.796093022208 megabits using the online calculator for metric conversions. Check the chart for more details.

116 MiB = 1020Megabit = 1Gigabit

dear sebastian:
thanks. you mean , 1gigabit switch port max speed is 110MB//s ? i think
Gigabit Ethernet Speed is 1Gbps. right ?
what differenct is gigabit, gbps , mib/s ? thanks. which switch i need to select for touch 1gib/s ? thanks.

Don't confuse the units.

Usually, upper case "B" means "byte", while lower case "b" means "bit".
1byte(1B) means 8bits(8b). These are NOT AT ALL specific for FreeBSD. And on serial data transfer like ethernet, redundant bits are added for error checking and correction. So 1B becomes around 10b.

And more, both IP (TCP/UDP) and ethernet are packet oriented, means, additional data for packet headers are added for controlling transfer.
So actual transfer rates are mutually always slower than line rate (for 1000base, 1Gbits/s).
