VDMA write throughput greater than read

Hello,

 

In several documents I found that the write throughput of the AXI VDMA core is greater than the read throughput. What is the cause of this difference ? I can only find it's due to the free run(ning) mode, but nothing about the actual mechanisms that increase the write channel throughput when the VDMA does not wait for external triggers.
