h1. Performance comparisons h2. D-LAN vs ApexDC++ h3. Setup 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. * We used two computers on a gigabit LAN. * There is a local DC++ hub: ADCH++ 2.8.0. * We didn't do any other operations during a transfer. * 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). * OS: Windows 7 64bits * Download computer CPU: Intel Core 2 Duo E8400, 4 GiB of RAM E8400 * Upload computer CPU: Intel Core i7 860, 6 GiB of RAM 860 * Apex version: v1.5.2.1276 (64bits) * D-LAN version: 1.1.0 Beta6 * Software used to count cycles: "Process Hacker 2":http://processhacker.sourceforge.net/ h3. Download speed We repeated the transfer three times. | |_. # 1 |_. # 2 |_. # 3 |_. Average |_. Average rate | |_. ApexDC++ | 160 s | 167 s | 163 s | 163.3 s | _20.1 MiB/s_ | |_.
