User (Legacy) Posted September 20, 2001 Report Share Posted September 20, 2001 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 Link to comment Share on other sites More sharing options...
Software FX Posted September 21, 2001 Report Share Posted September 21, 2001 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. -- Regards, JC SoftwareFX "Chris Strobel" <cstrobel@b2btech.com> wrote in message news:glFj1dgQBHA.1276@webserver1.softwarefx.com... > Are there any optimizations we can do for better performance with the > ChartFX Server component for ASP pages?
