J-10 is slightly faster than both Euro Fighter and Rafale due to the insanely powerful engine - It has a max speed of Mach 2.2 , while Eurofighter has a max speed of just under mach 2.0; and Rafale even lower of just Mach 1.8.
Rafale has much better T/W then J-10A (and B for that matter) . Therefore, Rafale would has better acceleration at subsonic and low supersonic speeds .
Reason for J-10 higher top speed is primarily in the wings . Rafale has larger wing area and wingspan with slightly cranked delta wing . On the other hand J-10 is more like classical delta fighter with canards . J-10 has good instantaneous turn rate and good handling at higher speeds , but in sustained turn fight it would loose against most of the current opponents . On the other hand, Rafale performs extremely well at low speeds (see demo below) Also, because of higher wing loading, J-10 could carry less payload then Rafale .
