Why Is Uploading Normally Slow

Most traffic flows from the Internet to you, broadband connections often have download speeds much faster than their upload capability. A typical "8 Meg" broadband connection would have an upload capability 20 times less than the advertised download speed, so more often than not - you are at the limit of your connection.

Remember that broadband speeds are measured in Megabits per second, and files are normally measured in Megabytes. There are 8 bits in a byte so you must divide your upload speed in Megabits by eight to derive the number of Megabytes you can upload each second.

Use the independent broadband speed testing service www.speedtest.net to establish your true upload speed. For example, a broadband connection with a measured upload speed of 400Kb/s means you can upload 400 kilobits each second. Dividing this by eight gives us an upload capability of 50 kilobytes (KB) - you should see an upload rate in this region when uploading to your online storage. 30 megabytes of photos would take approximately 10 minutes to upload at that speed (30 * 1000 = 30,000 kilobytes divided by 50 = 600 seconds divided by 60 = 10 minutes.)

Ensure you're Internet connection is not being used for other demanding tasks such as file sharing and watching videos when you are trying to upload to decrease bottleneck.

Always scan your computer with antivirus/antispyware programs to locate potential malware eating up your upload bandwidth.
