A Benchmark is a test that checks the performance of varying factors and can be compared amongst the like. A server benchmark tests the i/o speed (disk read and write speed), internet speed and checks what sort of system, memory and CPU the server has.
Once connected to your server via SSH in Putty paste and run either of these two commands:
wget -qO- bench.sh | bash
curl -Lso- bench.sh | bash
It will run through the benchmark and this will be the output shown:

It starts off with listing the processor, cores and the speed. After that we have the memory (ram) available and your server’s uptime. You then get some operating systems and kernel information then comes the speed tests.
It lists the locations, provider and the speed it took your server to download a file from that location. Depending on your servers location, network port and peering is what speed you will get.
Finally the Disk speed, this is the speed of reading/writing files. An SSD or NVMe will have a high-speed, HDD not so much.
