If you click on the Upload Files feature you will use our HTML5 (or Flash-based) upload tool, which we recommend for fewer, smaller files.
We recommend Upload Folders, a Java-based upload tool, for larger files, folders or a larger number of files. Note: Chrome works with Upload Folders but does not need Java.
Browser Specific Issues: Try a different browser or computer. Users may find that their upload speeds increase on alternative browsers.
Please ensure that your web browser is the latest version of Internet Explorer, Safari, Firefox or Chrome.
Device Specific Issues: If your upload speed has not improved after you have tried updating and/or switching internet browsers, please try a different computer to help isolate the issue.
If your upload speed increases on another computer, then you will know that the first computer itself was causing the slower speed.
If your speed does not increase, then this is most likely an issue with your internet connection.
Internet Service ProviderSometimes slow upload speeds are the fault of your Internet Service Provider.
We recommend a high speed internet connection with high upload speeds.
Often with Cable and DSL, the upload speed is significantly slower than the download speed. This will result in fast loading times for most websites and file downloads, but slow uploads.
A Note on Kilobytes vs. Kilobits
There is a difference between “Kb” (kilobit) and “KB” (kilobyte). One kilobyte is equal to eight kilobits. Internet service providers (ISP) often calculate and advertise upload and download speeds in terms of “Kbps” (kilobits per second) while Box uploads are calculated in terms of “KBps” (kilobytes per second). Therefore, if you are receiving upload speeds of 30 KBps this would be interpreted as 240 Kbps by your ISP.
Bandwidth and the Box Accelerator:
Upload speed depends on your network connection and a component of this is bandwidth.
Bandwidth allowance determines the amount of data that can pass from the Internet to your web browser in a given amount of time.
A smaller bandwidth results in a longer time that it takes Internet data to transfer on your web browser.
For business and enterprise accounts, Box has proprietary accelerator nodes that allow us to route your uploads through the fastest network route. To kick-start this feature, we suggest uploading approximately 9 files (between 2 and 6MB each) to your account, to initialize the accelerator node’s search for the best route. From there on out, your connection will route your uploads through the fastest route to Box. It takes only a handful of uploads per week to keep the Box Accelerator optimally tuned for your whole office.
