Lenses typically perform less well when close to maximum aperture (smallest f-number) which also results in a drop in sharpness. Where possible, the chart will include a red vertical marker at the Diffraction Limited (DLA) to indicate where diffraction will start to affect the sharpness of the image.
At small apertures (large f-numbers), diffraction will soften the image and reduce the sharpness.
