Factors that influence website performance.

Audio files
There are two audio types which again like image types both serve different purposes. A MP3 file is an audio file which is compressed digital data, allowing it to be of a smaller file. The larger the MP3 file, the longer it will take to download. A wav file is a larger file and is of a much higher quality than an Mp3 file. It will also take much longer to download this file, if the file size is larger than normal.

Video and Animation

There are three types of video and animation types which both serve different purposes, These include avi, swf and conversion between formats. Each of these file types can affect the performance of a website depending on the size of each of these files. If they are of a large size it will take longer to download than that of a smaller sized file.

User side factors

There are two types of user side factors that can affect the performance of a website. These include the modem connection speed and the PC performance factors. The modem connection depends on the speed of the internet connection. For example ADSL is a faster connection speed which means that the performance of the website will load in less than half a second. In comparison to this the dial up connection (narrow band) will take longer and will have a negative influence on the performance of the website. In addition to this the PC performance factors also affect the performance of a website due to the cache memory and other factors such as viruses. If a webserver has cache memory it will have a positive affect on the performance of a website as websites will be stored in that particular memory such as google causing the website to load quickly and efficiently. In addition to this viruses can affect the normal operation of the computer when browsing, therefore it will take the website much longer to load than normal when a virus is installed.

Server side factors performance

An additional reason to what affects how quickly a website resolves may be due to the performance of the webserver. For example network trafficing. This can slow down the webserver, take a long time to load webpages or not deliver a website at all, causing a negative affect on the performance of a website.
