Hello, |

Currently, I manage gentoo system that have a variety of 10 and 100 MB/s |
| 5 |
ethernet cards. I use lshw to distinguish the max ethernet port speed: |

For example: |

Is this reliable? What if a 10/100 card is plugged into a 10MB/s hub? |
| 63 |
|
| 64 |
|
| 65 |
Is there other software to discern the hardware capability and test |
| 66 |
actual throughput? |
| 67 |
|
| 68 |
How comfortable are you with the results you get? (reliable?) |

curiously, |
