Just my contribution: Due to the feedback from several other users regarding these issues, I have been postponing to update my platforms. Today I had some free time so I decided to make a test and updated one of my platforms to v2716. Then, I started testing and opened the very same chartbook in two separate instances (with my default settings) side by side, one with the upgrade to v2716 and the other with my current v2700. The immediate result I noticed was that with v2716 the CPU load was much lower than with v2700. I got really puzzled with it because it goes against any report made by every other users. Then I realized that there was a lag on v2716 when comparing the price movement (charts / DOMs side by side) with v2700 (both connected to the same SC server). So, I went through the new settings on v2716 one by one and made some experiments. To make this report shorter, in order to get a very similar performance with the two instances, I have to use the following settings: - Timer Management - Chart Calculation/Draw Time Multiplier for Interval Delay = 0.5 - Timer Management - Maximum Interval Delay in Milliseconds = 250 - Trade DOM - Had to reduce from 50ms to 25ms (half) - Main charts - Had to reduce from 200ms to 100ms With this settings, I get a very similar performance out of my main two chartbooks, whereas the CPU load becomes very similar in both instances. Just to make it clear, I tested twice with two different chartbooks (one at a time) and both with the "twin" charts and DOMs side by side. I haven't experienced any lag with the pointer and besides having to alter the mentioned settings, everything seems normal. To finish, I think it would really be a very good idea to have the High, Medium or Low priority option for the charts as mentioned by SC Engineering Date Time Of Last Edit: 2024-12-04 18:53:36
