Benchmarks
A benchmark is everything that gives you an idea about performance. For your Linux, you can use the following benchmarks:

Combined benchmarks
A quick and easy benchmark that combines the performance of all your computer's components is GeekBench.
Component benchmarks
CPU
This tests CPU and memory with a strong focus on addition:
# time (i=0; while (( $i < 10000 )); do i=$i+1; done) real 0m4.173s user 0m4.161s sys 0m0.000s
RAM
# dd if=/dev/zero of=/dev/shm/test count=5000 bs=8k 5000+0 records in 5000+0 records out 40960000 bytes (41 MB) copied, 0.0175427 s, 2.3 GB/s
disk
- hdparm
- IOps - random read performance in IOPS and MB/s
file system
- bonnie
- iozone
- iometer
networking
Throughput
Use netcat, for example on the receiver:
netcat -l -p 8000 >/dev/null
and on the sender in the bash:
dd if=test bs=1024K count=512 > /dev/tcp/192.168.0.9/8000
a result can be:
4887552 bytes (4.9 MB) copied, 4.3689 s, 1.1 MB/s
An interesting thing is that if you forget the >/dev/null you will come to a pretty constant value which is useless because it tells you how quickly the shell can write nulls.
latency
- ping
MTU
Increasing the MTU helps reducing the need for ACK packages and reduces interrupt storm on the processors.

Graphic card
Watching a video feels sluggish on one computer, but on the other it is okay ? Test your graphics card with glxgears like this:
$ glxgears 359 frames in 5.1 seconds = 70.397 FPS 320 frames in 5.1 seconds = 62.590 FPS 320 frames in 5.3 seconds = 60.201 FPS 320 frames in 5.1 seconds = 63.046 FPS 300 frames in 5.4 seconds = 55.305 FPS 340 frames in 5.4 seconds = 62.724 FPS 300 frames in 5.2 seconds = 57.543 FPS 340 frames in 5.4 seconds = 62.483 FPS 320 frames in 5.1 seconds = 62.149 FPS 320 frames in 5.2 seconds = 61.365 FPS 300 frames in 5.1 seconds = 59.275 FPS 320 frames in 5.5 seconds = 58.109 FPS 320 frames in 5.1 seconds = 62.149 FPS
