| 8 | 5 | Greg Burri | We measured the transfer time and the number of CPU cycles for *one* transfer of a 3.2 GiB file. The performance of both systems may varies in a concurrent downloading and uploading case. |
| 9 | |||
| 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 | 2 | Greg Burri | * OS: Windows 7 64bits |
| 16 | 4 | Greg Burri | * CPU: Download computer: Intel Core 2 Duo E8400, Upload computer: Intel Core i7 860 |
| 17 | 1 | Greg Burri | * Apex version: v1.5.2.1276 (64bits) |
