An A320 departed Runway 1 left PORTE3 SID. In the next departure hole - after landing traffic on Runway 28L/R; a B757; departed Runway 1L on the PORTE3 SID. Upwind four miles; a B757 was about 1-2 miles east of the A320 who was incredibly slow and turned on a dime. I do not know whether or not a loss occurred in NCT airspace. Is it the aircraft -or- the pilot? Either way this is an example of a dangerous situation where Airbus aircraft are neither performing to their capability; and nor meeting the needs of the NAS.
SFO Controller voiced concern regarding the flight characteristics and/or pilot techniques of the A320 with regard to SID compliance.
