DS412+ works with ASUS C2500, but is slow #413

Open Sailing74 opened 3 months ago

Driver package installed with no problems on a DS412+ (r8152-cedarview-2.17.1-2_6.2.spk). ASUS C2500 links with 2.5 GBit/s with the switch. However, actual speed is in the range of 80 to 90 MB/s. Speed measured with iperf shows appr. 800 MBit/s. Built-in LAN has higher performance.

Too bad. Maybe the 412+ is too old for these speeds...

USB performance does not seem to be sufficient for older platforms. Perhaps USB-connected HDDs are about the same speed.
