Post From: CPU usage on an AppleMacbook PRO

I spent a few hours opening & closing my various workspaces & watching the CPU Usage in the Task Manager. What I found what was eating the CPU cycles was the "Chart Update Interval". It was set to 40 ms. My 6 year old 17" MacBook PRO was also set to 40 ms. The 17" MacBook did not have the fan/heat problem. My guess is that this new MacBook has 4x the pixels to push ... & maybe Sierra Chart doesn't do much with the current GPUs. I found that by changing the Chart Update Interval to 750 & higher the CPU usage really drops & the fan speed barely moves any higher. Yay. I don't believe I ever changed the default setting, and I contacted one other user and his setting was also set at 40. I'm saying that because of the below statement that is in the support documentation. ------ "If you are using a Chart Update Interval under 100 ms, then please do not contact support for high CPU usage problems. Be aware that using an extreme setting like under 50 ms is not regarded as efficient and you should be aware of the potential negative consequences with CPU usage that this will cause. In other words, use these more extreme settings at your own risk!" |
