The Numbers Bars study consistently adds 25ms to my Average Calculation and Draw Time in the Performance tab of the Chart Settings window. The VBP study also runs at 10ms, but I'm less concerned about that one. I have seen other threads regarding Numbers Bars and overall Sierra performance improvements like these: Performance Problems with Numbers Bars Recommendations to Improve Overall Sierra Chart Performance I have tested and changed tick size, number of days to display, removed all unused studies, tested OpenGL on/off, and am using a stripped down Windows install. The machine has 24 CPU threads, 64GB ecc ram, NVMe storage. I have tested different Nvidia and AMD GPU's, though older generations. CPU performance is about 20% off the fastest single core geekbench. The CPU cores usually peak in single digit usage, and GPU hits 30% with this study and OpenGL enabled. I have other charts with dozens of all kinds of built in studies, alerts, spreadsheets, and custom compiled code, and they all run fast. ie. Charts with 10, 20, 50 studies, run at 6ms, 10ms, 15ms. If I run one chart, with just the Numbers Bars study, it runs at 25ms. This is at full screen 4k resolution. The draw time improves the smaller the window is. I would happily upgrade the CPU to get the last 20% of silicon performance, or the GPU if a generational upgrade makes a huge difference with these calculations. But seeing as the performance is isolated to 1-2 studies, and is 10x to >25x slower then any other study I use, this seems more like an optimization issue in the study code, or user control. Any ideas, or benchmarks of drawtime at 4k with the numbers bars study with different cpu/gpu combinations out there? |

Numbers Bars involves a lot of text and text is simply inefficient. If you remove the text that will make a difference. The problem is the text, and the use of a 4K monitor.
