Swift different quorums does not show change for write intensive workloads

I am doing some experiments with openstack-swift. My cluster has 5 storage nodes and 1 proxy. I performed 90% writes and 10% reads to the cluster using ssbench. The results I obtained with Read Quorum 1/ Write Quorum 5 and Read Quorum 5 / Write Quorum 1 does not show any significant change at all. But for read intensive tasks like 90% read and 10% write the results shows a very big difference. I am confused with this behaviour for write intensive work. Anybody have an idea?
