Why Are Most Cloud File Transfer Services So Slow?

At first, we must know that the cloud file transfer services you use are from different cloud services providers, such as AWS of Amazon, and Azure of Microsoft. So when you find your cloud file transfer services are so slow, there are many points you need to pay attention to.

Speed & bandwidth limitation

The first and most important reason is the cloud service provider will limit your cloud transfer service speed. You must pay more to upgrade to their expensive plan. For normal users, it will only provide basic speed, like, around 200kb. Another common reason is some cloud service providers can not make full use of your bandwidth, so even if you have 150Mbps bandwidth, it may still cost you a whole day to transfer a 1Gb package.

File size

Of course, file size is always a key factor. Some file cloud service providers can handle small files easily, but when files go up to TB-scale or even PB-scale, the transfer speed will become really slow. This is because those cloud service providers do not have high-performance servers to support large file sharing.

Transfer protocol

Many cloud transfer services use the FTP or TCP protocols. This is also the main reason that affects your file transfer speed. FTP also has security problems.
