Electrostatic Induction: Conductor vs. Dielectric Response Time

[Samson4]

Do electrostatic fields induce charges on conductor surfaces faster than dielectrics respond to an identical field?

Conduction electrons adjust in femtoseconds or less; I suspect that dielectrics respond slightly slower.

You cannot detect the difference by electronic means; it would require optical experiments.

Thanks Ultrafast. Am I correct in assuming that if a conductor is cooled, it will react faster to electrostatic fields?

If a field is changing (which is necessary to reveal any delay), it is no longer 'static'. The term is just 'electric field'.
