Android download performance
Hello. Using SFTP to download files from our SFTP server and are experiencing slow downloads on Android as if it is only downloading one chunk at a time. Our application is operating as expected in Windows and iOS. Are there any settings that we can tweak to help the download speed on Android?
Are you using SftpClient.DownloadFile? Any other method does download one chunk at a time (at the time of writing).
Aside from that, SftpClient does have a BufferSize property (and there are other internal properties) but I would not know whether the existing values are somehow sub-optimal on Android
This is assuming that the device has bandwidth to spare
I am using SftpClient.DownloadFile.
I have tried setting the BufferSize to 1MB and 4MB, but still not getting equal performance on Android device as opposed to other devices. What other properties can I look at?
Ok, you are using the best method, and actually the BufferSize does not make any difference above 64KB. I think your best bet is to measure bandwidth / latency / TCP window size. These will help inform you whether the network is the bottleneck or something else.
