Server Component Optimizations


User (Legacy)

Recommended Posts

Are there any optimizations we can do for better performance with the

ChartFX Server component for ASP pages? For example, we noticed that by

changing the server computer to 256 colors instead of true-color (16

million), that the time for the GetHTMLTag call was cut in half. Before the

change, it took almost 4 seconds to create 4 graphs, now it takes about 2

seconds. Is there a way to force it to 256 regardless of the server

settings? Are there any additional changes we can make or possible hardcode

to make ChartFX faster?

Thanks,

Chris

Chart.ImgCompression: If you are generating PNGs this property will allow to

fine tune the compression applied to the image, 0 means no compression and

100 means full compression. Please note that 0 will create bigger files so

you may end up slowing down the process.

Chart.ImgColors: Set this property to 24 if your clients will have 16bits or

better display cards, at the same time your server should be running at the

highest setting. If you are generating palettized images (default ImgColors

= 8) then you already found out that setting the server to 256 colors speeds

things up

Chart.GetHtmlData. This approach (as opossed to Chart.GetHtmlTag) does not

save any files in your hard drive so it should speed things up, the drawback

is that you will have to build your pages in a two step approach. Search on

bitstream or GetHtmlData in our support site for samples.

We are currently retesting ChartFX Internet in multiple scenarios (single

CPU, multiple CPU, Application Center, etc.) and expect to have a

performance whitepaper soon, at the same time we are evaluating some

technical possibilities to drastically increase ChartFX scalability. In the

near future we may run a beta for these enhancements so we are open to any

ideas/suggestions/benchmarks.
