The bottleneck is usually the network capacity, so clustering and distributed queueing performance is very similar. I've never heard any complaints that one is slower than the other.
The *disadvantage* of clustering is that if it breaks in a big way it can be harder to fix than distributed queueing. Cluster commands must be used with caution. The moral is to keep the fix pack levels as up to date as possible as there have been a lot of APARs for clustering.

using cluster advantages are it reduces creation of objects like remote qm, transmission q, sender chhannel, reciver channel so admin related tasks will be reduced and in fail over of one repository another repository will handle requests.
disadvantages in case of any natural disaster backup and recovery will be diffcult. |
