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
* Upload computer CPU: Intel Core i7 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.
