Percentage improvement 2010-08-26
shahrukh pose la question :
Hi...

We had a web page that was taking 12 secs to load. Now it loads in 3 secs. What is the percentage of improvement or how much faster is it working now. TO me it looks like it is working 3 times faster or there is a 300% improvement in the loading time. However my client says its ((12-3)/12*)100 = 75% improved. Which seems illogical on the face of it.

Thanks for your help
Shahrukh

In a 1998 survey, 21% polled responded favorably to a question. In 1999, 31% responded favorably.

What is the percent of improvement?
