Hi,

I've been looking at tpstats as various test queries run and I noticed
something I don't understand.

I have a two node cluster with RF=2 on which I run 4 parallel queries, each
job goes through a list of keys doing a multiget for 2 keys at a time. If
two of the queries go to one node and the other two go to a different node
then the pending queue on the node gets much longer than if they all go to
the one node.

I'm clearly missing something here as I would have expected the opposite

cheers
