HW: 1xLS2088 CPU (8xA72 Core:1.8GHz, Bus:700MHz) with 2x 4 Lane PCIe 3.0 (2x~31Gbit/s) 2xDDR4 memory block (64bit+ECC, 1.8MT/s=(2x115Gbit/s) There are two parallel scatter/gather DMA data transfer processes: 1. DDR4(1) write from PCIe(1) 2. PCIe(2) write from DDR4(2) What is the achievable native data throughput rate (maximum and average estimated with all overhead)? Where is bottleneck? (Our HW is in production but we have to answer to an important RFP now.)
