You can set up Jack to guarantee a maximum roundtrip delay of say: 4 
milliseconds. As Jack runs with such settings, all applications in the 
session have to keep delivering the desired data fast enough to keep 
that deadline.

CPU and company have to process the data so you will find out soon 
enough, if their powers suffice to provide the needed data within the 
limits, you have set up for Jack....

So if you have just one sampler playing preprocessed data without any 
filtering etc, you can set up Jack with very small buffers to get very 
little delay between pressing a key on a MIDI-Keyboard and hearing the 
played sound. Even on a lesser machine.
If you play with a complete band using Hydrogen for the drums, AMS and 
CALF and Yoshimi as Synths and guitarix and Rakarrack for the guitars. 
Recording all this seperately in Ardour while some 30 tracks previously 
recorded are being heared too, you need much more CPU-Power to keep the 
fun alive if Jack has to run with buffers for 4ms delay....
