I replaced all six original shocks and springs on a 1988 Jaguar XJS for someone. It was a big job. The results were dramatic. The old shock (on the right) had a lot less nitrogen pressure in it yet it extended much more quickly. No shock dyno required. BTW both sets are German made Sachs.
@JeepinDG No, you need to look how much pressure it needs to be compressed, a worn shock will compress easier. You also look how it it's capable of going back up, if it does get back up really slowly it is worn.

Shocks are suposed to slow the suspension to slow controlled movements, o blown shock will move very quickley and easyly, ---that is why the old shock moves faster ---- it is not slowing down the movement and working correctly.

A new shock will normally have more O ring resistance which would cause you to see what you're seeing.
