there could be a number of reasons, not least of which is the size of the cluster.
You could have a lot of disks out there on each node
You could have large networking traffic
You could have issues with name resolution if using DNS and not the hosts files.

One small test is to do a cmquerycl on the local node only and see how long that takes, then do it to just on eof th eremote nodes and compare.
You could also look at trying one of the options such as -k to reduce disc probing.
man cmquerycl for an explanation
