| 8 | 6 | Greg Burri | We measured the transfer time and the number of CPU cycles for *one* transfer at a time of a 3.2 GiB file. This is a particular case, the performance of both systems may varies in a concurrent downloading and uploading case. |
| 9 | 5 | Greg Burri | |
| 10 | 1 | Greg Burri | * We used two computers on a gigabit LAN. |
| 11 | * There is a local DC++ hub: ADCH++ 2.8.0. |
||
| 12 | 4 | Greg Burri | * We didn't do any other operations during a transfer. |
| 13 | 1 | Greg Burri | * We download/upload only one file at the same time. We cleared queued and file before each measurement (the file is deleted from the trash). |

| 15 | * OS: Windows 7 64bits |

| 16 | 6 | Greg Burri | * Download computer CPU: Intel Core 2 Duo E8400 |
