Dear colleagues , dear support ,
I have an essential question regarding the improve of performance of a desktop PC for use of Jforex JAVA platform. Now my PC is cofigured with an i5-3570K CPU (slightly overclocked), 16 GB RAM and a Nvidia 750 GPU , three monitors attached to it. I use a lot of undocked price charts (15+) with many objects on them , indicators , lines , pivots... etc. When I start to scroll a chart I observe an unpleasant stuttering and delays (less obvious with less separate or undocked price charts). So my questions are: 1. Is Jforex JAVA a multithreading program or singlethreading , means what will be better for performance, a more cores+threads CPU or a less cores+threads CPU but with higher single core frequency (for example i7 vs i5) 2. Is the Jforex JAVA program CPU dependent or GPU dependent , where are the main calculations made - in CPU or GPU , will an upgrade of the video card improve the performance of the program or it is mainly CPU dependent. Thank you in advance !

For the first - try increasing limit of memory used by Jforex Java process: Settings -> Preferences -> Advanced + Show Java Heap Size

Thank you for the reply mtnfx , of cource since the beginning it is set to the maximum 4096 MB , probably will be a good idea for the programers to increase the possible buffer to 8192 MB. The main question is actually - more CPU single core MHz , more CPU cores+threads , better GPU.

The platform is CPU dependent. It is both - single and multi-threaded. The calculations are multi-threaded. The display - single. It all depends on what exactly the platform is doing when there is a slow perpormance. Can you provide the workspace .xml file for investigation? If yes, send it to [email protected] plz. If you are using the price based periods, the calculation might take time, as all the calculations are done on the platform side. Once they are done, the results are saved on the disk. Next time the same period is used, the results are read from the cache. That's why a fast SSD is important as well.

Thank you for the reply dear support , I have already upgraded my system (CPU (fastest sigle thread) , Video card , RAM etc...) I think this is the key: "The display - single." , visible on the screenshot. Thanks once again

Would you mind sending us the workspace .xml file? We will check what is loading the CPU so much. Might be some indicator.

Re: "When I start to scroll a chart I observe an unpleasant stuttering and delays" I have impression that Jforex platform has major performance issue with loading of tick/bar data from "local cache" and "from internet" for locally missing portions. See my recent post here https://www.dukascopy.com/swiss/english ... 00&t=57625(and I do not think this can be fixed by very-best hardware)
