SharePoint and Bandwidth Optimization

Microsoft SharePoint becomes more popular by the day because it offers so many advantages for a distributed workforce. When considering whether or not to adopt SharePoint, a primary concern is performance. How long will users have to wait for documents to upload and download and how fast will initial page loads take? Even installations, where the performance is acceptable, can see dramatic improvements with Acceleration Systems optimization running. Who doesn’t want to make their workforce more productive?

A big portion of SharePoint performance, as much as 80%, is usually attributed to front end performance. In other words, how fast will the page load on a browser? Page load performance varies depending upon how many HTTP requests are involved and the latency experienced between the browser and the server for each of those requests.

In instances where custom pages and third party web components are incorporated into SharePoint objects, web pages may take 100 or more HTTP requests (JavaScript, CSS files, images, 3rd party content) to load. On a fiber connection, users notice the delay, but it’s manageable. But consider pulling down pages over an LTE link. Latency in the range of 125 ms is common. That translated to 12.5 seconds for a page with 100 HTTP requests. Coffee break, anyone? If meta tags or headers are not set up correctly, even with cached browser content repeat views may not be much faster than the initial load.

The other issue with SharePoint is the time it takes to upload and to download documents – especially large files like PowerPoint presentations. Transferring these files can take many minutes depending on the bandwidth and latency of the network. Without acceleration, you run the risk of running out of coffee if you move big files very often.

Cloud-based bandwidth optimization from Acceleration Systems addresses all the challenges associated with SharePoint use in remote offices and from the road. We incorporate application layer optimizations specifically for SharePoint and HTTP to improve front end page loading. Deduplication of dataadvanced compression techniques, and data caching dramatically reduce the amount of data transferred. These data reduction features can result in up to 90% data offloads. That makes the workforce more productive and saves on coffee.
