10 years ago6.0GB/s for Gen 3x8 for both read and write seems reasonable.
For the machine that get a slow throughput, it could be the link was trained to gen3 intially but was later downtrain to lower speed (gen1 & gen2 only). Try minitor currentspeed signal continuously to ensure the link not downtrain. Also can try to monitor the LTSSM to ensure the link does not goes to Recovery state too often.
