This markup is easier to understand and is supported by all modern browsers, but may not be supported by all content management systems. If for whatever reason, you cannot add the download attribute in the case that you cannot directly edit the HTML of your web page , you can optionally compress the file using zip, and instruct the user to download the zip file. You can alternatively explain to the user that they should right click on the link and select download.
If you have no other alternatives to force the file to download, you can host it on a file hosting service such as Google Docs. The most common file types that are affected by this behavior are PDF files and images. The code below will tell the browser to prompt the user to save the file. This link does not have the download attribute. ISPs can fall behind on adding capacity and this can lead to degraded performance. As a real-world example, Comcast customers have complained about poor performance.
Netflix and Comcast pointed fingers back and forth about whose fault it was, but it was really a protracted negotiation about who should pay for the increased capacity required to support growing Netflix usage. In the end, Netflix signed a commercial interconnection agreement with Comcast. Since Netflix signed the interconnection agreement with Comcast, the speed of its customer connections has improved dramatically.
The bottom line here is that ISP business decisions affect the experience when using different services. This is most noticeable with services like video applications where large files must be delivered in real-time. Some ISPs throttle, or intentionally slow down, certain kinds of traffic like BitTorrent or other peer to peer applications. If you are a regular user of these applications, try shutting them down to see if this improves your connection speed.
Likewise, some ISPs may actually slow down your transfer rates once you have passed a certain usage threshold. If you suspect this is the case, you might want to get in touch with your ISP to see what the limits are. The long and short of it is that not all ISPs are created equal when it comes to things like capacity, peering, interconnection agreements, caching and traffic management.
The actual throughput you get may not meet your needs during prime usage periods. Upload and download speed is also affected by the distance between your computer and the server that is either sending or receiving data. In general, the greater the distance the slower the speed of the data transfer. When connecting over larger geographic distances, traffic makes more hops between different connections, and each hop increases latency.
Your data can take a multitude of different routes between your computer and a remote server. Sometimes transfers simply get caught up in congestion along the way.
As a result, users of one ISP may fast upload and download speeds from a site, while users of another ISP may see a temporary glitch in performance. Probably the most important one is to use a content delivery network. Instead of serving all media from one location, popular content will be cached in different points of presence around the world.
When a person requests a file, it is automatically served from the location that will provide the best performance barring some sort of congestion, this is usually the one closest to them.
Again, on average, the shorter the distance, the faster and more reliable the upload. The protocol that is used for uploading or downloading a file can also have an impact on the speed of data transfer. The protocol is great for reliability. Transfer speeds can be accelerated over fast connections at least 5 Mbps by using the UDP protocol. Aspera, Signiant, and File Catalyst all offer accelerated file transfer solutions that are geared at companies that need to send vast amounts of data back and forth between different locations.
In order to take advantage of the potential speed of these services you need a fast connection. Check with your ISP to see what package you have subscribed to. Note the upload and download speeds. Most residential and small business packages have much faster download speeds. Test your connection speed via Speedtest.
This will help isolate whether the speed issue is with your ISP or with your wireless network. Check the placement of the device, try changing the network channel, and make sure you have the latest drivers for your devices. It will be helpful if you can provide information on whether the problem happens when connecting to sites in general, or if the poor performance is limited to certain sites and applications. BTW the link that you provided works fine for me. I am using high speed though, I could download it almost instantly.

Hi, Suppose I have a webpage , One time I set an Image as an image in the page and another time I set it as a background image. If all other specs are the same, will there be any differences between the download time of the page? Share Flag.
