You can find lots of information in the User Guide (420-page PDF). Page 57 shows the performance effects: Atlas V 400 series performance is based on the use of the 4-m EPF. GTO performance with the LPF is approximately 35 kg (77.2 lb) more than the EPF with the 401 configuration and 44 kg (97 lb) more with the 431 configuration. GTO performance with the ...

You're forgetting that on top of their mass being different, larger ø also means larger cross sectional area, and with it increase in aerodynamic drag. So larger ø ones are heavier, subject to stronger atmospheric resistance, have larger contact area subjected to ascent heating, and with a more contoured launch vehicle's body deviate from ideal aerodynamic ...

While other answers are perfect from an engineering point of view, there is another aspect. The 4m and 5m fairings have different designs and are produced at different sites. 5m fairings have aluminum honeycomb core and graphite epoxy face panels and are made in Emmen, Switzerland (RUAG), the same manufacturer that makes Ariane 5 PLFs. Basically, this is a ...

No, they don't. Here is the RUAG Space page for fairings: https://www.ruag.com/en/products-services/space/launchers/launchers As we can see, no mention of reusability. Also no mentions it's planned in future. As all the other fairing manufacturers in the world except of SpaceX, they produce new fairings for every launch. RUAG fairings are not recovered, they ...
