From: Igal Liberman <igall@xxxxxxxxxxx> When enable_single_wr is not enabled, the DSE will only write those parts of a result descriptor that need updating, which means a final result descriptor will be written in 2 or 3 smaller transfers. When enable_single_wr is enabled the DSE will combine these 2-3 updates into one large write transfer, generally improving performance.
