I can’t even figure out how to speed up my computer’s download rate.
Last night I was setting up my new Samsung S22Ultra cellphone. I decided to test to network limits. On my wireless network it downloads 131 Mbps uploads 100 Mbps. I turned off the WiFi and tested National 5G. 108 Mbps download/3.91 Mbps upload. Final test is I plugged my USB C to 1 Gbps Ethernet adapter on the phone. Download was 640 Mbps/upload 980 Mbps. I think download is hobbled by the speed of the onboard memory in the phone. The upload performance of 980 Mbps matches my best i7/i9 desktops on the same wired network. The wired network attached to a fiber optic 1 Gbps symmetic connection.
CPU, network interface, disk technology (nVME/SATAIII) have different throughputs. nVME will move 1400 MBps to/from disk. The 6 Gbps link speed of SATAIII hobbles the speed of the SSD that it interfaces. Typically about 600 MBps to/from the SSD. The disk link speed of SATAIII is still 6x faster than my fiber optic network.
