Basics Web Performance
We need to know why do we care about the performance. While fast web sites makes customer happy there are other benefits of better performance , They saves your money by
1. consuming less bandwidth
2. Consuming less servers
Better performing websites also help in generating more money ,
According to recent survey done on two web site Google and Amazon ; In amazon it was observed with every 100 ms increase in load time of Amazon.com the sales got decreased by 1% in another incident the home page of goggle maps when decreased from 100KB to 70-80KB traffic went up by 10% in first week and additional 25% in following three weeks.
Your web site performance also impact the ranking on Google. Now we know the importance of performance lets have a look at what makes web sites slow
The general assumption is the performance of website can be improved by tuning the code on server side.But with recent research it has been found that 10-20% of total response time is invested in processing the request generating the HTML and getting it download. While rest of 80-90% time is invested on getting auxiliary files like image , javascripts, css etc. To demonstrate this we need to use the tool to see the conversation that happen b/w the browser and server. The conversation between the browser and server happen through HTTP protocol . The protocol stands for Hypertext Transfer Protocol ; it is text based protocol so we need some tool which can help profile http traces and one of the tool is Fiddler. This tool can watch the conversation that happen b/w browser and server
This tool is free and can be downloaded by doing small search on google ; The tools has various features
1. You can watch the web traffic
2. Shows complete request and response
3. Can save the session which can be used to compare the performance before and after
4. Transfer Timeline : graphical view of all the request made
5. Statistics is another feature in Fiddler.
We will talk about the fiddler and how we can see the response time on next post.....
