Cycle times are supposed to be just as fast or faster than a 335. There is adjustments for the pump but are pretty intricate because adjustment of 1 thing such as max flow changes all the other settings in the pump and can really rob horsepower. Also each valve spool is metered to only allow maxium amount of flow reguired for that fuction's cycle time. You could have a pump set too low or pilot pressure may be low and not stroking valve spools fully open.
It would be better to have the dealer check it. He has the cycle time specs in his service manual and can reset it if need be. If this is a new machine it would be a warranty repair if the times were off.
