To get started, you first download the Portal app from Google Play, then visit. There are also no file limits in place, so you don’t have to worry about whether or not a file transfer will work with Portal. That makes it especially useful for things like loading a video onto your phone ahead of your flight, for example. However, that also means that Portal is better at handling very large files or many files at one time.įiles moved with Portal are transferred much faster over Wi-Fi because there’s no uploading and downloading as with Pushbullet, CEO Ryan Oldenburg explains.

That means both your computer and phone have to be connected to the same network in order to use the app, while Pushbullet doesn’t have this limitation. While the company’s flagship app Pushbullet also supports file transfers, what differentiates Portal is that it uses your local Wi-Fi network to make the file transfer. Launching first on Android where it’s able to more deeply integrate with the OS, Portal is designed to make it easier to move files – even large files – between your computer and your Android phone. But if there’s a big discrepancy between the bandwidth and the network delay, even that 1 MB can be too small to saturate the bandwidth.Pushbullet, the company that makes a handy utility that moves notifications, links and files between devices, is out today with a new app called Portal, which focuses on file transfer alone. For example WinSCP can request up to 32 chunks for 32 KB each at once, totaling 1 MB (these are defaults which can be altered with SFTPDownloadQueue and SFTPUploadQueue raw session settings). Most SFTP clients (including WinSCP) overcome the problem by both requesting/sending a large chunk of the file in each single read/write request and by sending (queuing) multiple requests without waiting for a response to previous. If the client spends this time uselessly waiting, your transfer speed will be low.

When transferring, the SFTP client (WinSCP) sends a read/write request to the SFTP server, waits for a response and repeats, until the end of the file.Įven if your connection is fast, if the server is far away (or slow), it takes a time for the response to arrive back. Network delay/latency affects particularly SFTP, as it is a packet oriented-protocol.
