Hiya, I have been working on my setup and found that SC has been lagging on me. Dragging charts around, placing and removing orders on the ladder. It has a small delay of half a second to a couple of seconds. I have been through the "Help topic 30: for High CPU Usage" and adjusted where possible. The only part that confuses me is 30.37 on determining cpu load on Sierrachart. At this point I have 6 monitors powered by 2 nvidia quadro's so I wouldn't expect it to be a GPU problem. Each monitor is 1 separate instance to distribute the CPU load as stated in the documentation (6 instances total). Each instance has 2 charts books each with 2 TPO Charts, 1 footprint, 1 range and 1 time chart (5min) and 1 spreadsheet. The spreadsheet has been reduced to the bear minimum of calculations with studies not included if they are not needed. Ram wise I have 16GB. CPU wise, I have a AMD Ryzen 5 -3600 6 core processor with 12 threads (runs at 3.81 GHz). When SC is up and running, the CPU produces between 15% and 30% workload. The documentation states that you need to divide 100% by the amount of threads (which is 12), and the number you get is the max amount your CPU can be running at. In my case that would be 100/12 = 8.3. So I could conclude that I need a better CPU that makes sure SC runs under 8% on it. But this seems analogical to me. If the CPU is only used for +-25%, why would a stronger CPU with more cores would be necessary? Trading now is workable, but the lag is very inconvenient. Any idea on how to fix this? Like I've said before, I have been through the help topic on High CPU usage and have made adjustments where possible. (This --> High CPU Usage | Inactive User Interface | Poor Performance | Long Time to Load Chart Data | Charts Reloading Often) Kind regards Lander |

Other than help topic 30, no we do not have any idea what to do. There is nothing further we can do.

What is the total overall CPU usage? The 15%-30% CPU usage on SC will not lag a computer at all. Show you Task Manager When you are seeing the LAG. Are you surfing the internet? Is a Anti-virus running in the background? IS the "SYSTEM" using alot of CPU? |

Overall CPU usage is between 15-40% with only SC running. Antivirus is windows defender with the entire SC folder excluded. As they state in the documentation, CPU usage should be below the 8% on my system. But that seems highly unlikely that sc only runs smooth if it's below that... |

I would never use Defender ever as it is very CPU intensive, and never let it run during trading hours. I used to run lots of bells and whistles and charts on SC. I found out that never made me a good trader just added to ADD symptoms. What does Chart Settings-Chart Setting 4 tell u as far as calcs per second? Only time I have ever seen true lag was when I used OEC data. |
