Yes, the performance of ECC is much swifter than that one of conventional asymmetric cryptosystems as per http://www.ijser.org/researchpaper%5CPerformance-Based-Comparison-Study-of-RSA-and-Elliptic-Curve-Cryptography.pdf
ECC requires shorter key to achieve security as compared to RSA, and that the mathematical operation involved in ECC is scalar multiplication while RSA uses exponentiation. Because of these, computational complexity involved in ECC is much less as compared to other asymmetric cryptosystems.
This enables much faster encryption, decryption and signature verification. Also it saves bandwidh and memory space.
Hence ECC is best suited for devices which have limited storage and computational power (like smart cards). Also it is suited for web-browsers, which use a number of encryption sessions.
