Question: Should uploading files via a FTP program be slow?
Answer: It depends on your Internet upload speeds and your web host. If your broadband Internet connection is capped at 5 Mbps than you won’t be able to exceed this limit. Another factor that can make your FTP uploads feel sluggish is your web host.
If your web host has a over saturated server then your upload speeds may be impacted. The more users trying to upload or reach a web server will make the server more slow. To determine if the slow down you are experiencing is because of your ISP or your web host. You can try identifying when the slow down occurs or if it is every single day.
Now try uploading a few files from your home, office, or a local coffee shop. See if there is any noticeable difference in the speed and if any slowness can be observed. It all all three locations you notice the speeds are always slow then its probably your web host and not just you.
