New data is uploaded each week. That looks like quite a useful bit of code. Can you do the same with swf's?
I'll not bother implementing it at the moment though as the slow down seems to be downloading the swf's and not processing it but I'll keep it in mind for the future.

Is this because the server is > generating them each time the page is called? Just an idea: Will the information in the graphs ever change? If not you could generate the graph and write the output to a different file and include that directly in an <img> tag. E.g., this is a basic example that only "regenerates" the graph if the appropriate file doesn't already exists: <!--- define the name of the image file ---> <cfset variables.chartfile = "myimage.png"> <!--- already got hte graph? ---> <cfif NOT fileexists(expandpath("myimage.png"))> <!--- generate the chart ---> <cfchart name="variables.chartbuffer" format="png" ... > ... </cfchart> <!--- write to a static file ---> <cffile charset="ISO-8859-1" action="write" file="#expandpath("myimage.png")#" output="#variables.chartbuffer#"> </cfif> <!--- output the image ---> <cfoutput><img src="#variables.chartfile#"></cfoutput> Doing this will save execution time on the server and you could also generate a seperate graph for each driver, for example.
