Support, I just upgraded from version 2168 to 2192 and platform is having tremendous performance issues. I literally no longer able to load any of my previous chartbooks that worked perfectly fine on version 2168. It takes almost an hour to open old working chartbook and after that platform feels extremely sluggish of freezing up entirely. Even starting platform without any chartbooks now takes anywhere from 5-10 min - this is ridiculous! I have restarted machine several times and made sure nothing else is running. I am barely using 10% of CPU and 25%-30% of available 24 GB RAM. What have changed in these 24 versions that makes the platform completely unusable? Please advise. Thank you. |

Nothing has changed which is actually causing any real performance issue. The performance is actually improved. We suspect the issue is what is explained here in the first note for 2187: https://www.sierrachart.com/index.php?page=doc/Whats_New.php#SCVer2187 What is happening, is file compression is being performed by the operating system in the background. Depending upon the speed of your system and drive, will affect how long it will take to complete. That is what is causing the performance issue. It is the operating system compressing files in the background. Normally this should just simply take no more than a few minutes.

Support, That is NOT an answer that addresses the issue. I do not find acceptable the explanation that simple upgrade from one version to another is somehow initiated mystical Operating System file compression forces in the background rendering platform and perfectly stable chartbooks completely unusable. I have not changed anything in my setup except upgrading Sierra from 2168 to 2192 and the entire setup I have used up until this moment (several months) is no longer working. This leaves me completely dead in the water right at the beginning of trading week and instead of trying to address the problem or at least attempt to investigate you sending me on a fishing trip looking for "recommended performance improvements". I don't need performance improvements, I need my platform and setup to function exactly (or better) as they were BEFORE the upgrade to a higher platform version. There was nothing changed from my side except new version of Sierra. The hardware is also more than adequate. Why is the chartbook that used to take several min to open now takes an hour? Why is the platform WITHUOT any chartbooks now takes 10 minutes to start? How can I resolve this? Date Time Of Last Edit: 2020-11-09 08:12:36

We have given you a proper answer. If you want to discontinue Sierra Chart, please do that. If you want to believe it is not related to file compression and it is something else, and we do not know because we do not know what is happening on your system at the moment, then you need to work through and troubleshoot this yourself.

How is this a proper answer if the ONLY thing that was changed was Sierra chart version? Version 2168 works fine and version 2192 does NOT? Could you please explain why is this a user responsibility to troubleshoot a problem caused by a version upgrade rolled out by a vendor? |

Could you please explain why is this a user responsibility to troubleshoot a problem caused by a version upgrade rolled out by a vendor? This is answered here:High CPU Usage | Inactive User Interface | Poor Performance | Long Time to Load Chart Data | Charts Reloading Often: 30.44 - Performance Differences Between Versions of Sierra Chart and at the beginning of the section here: High CPU Usage | Inactive User Interface | Poor Performance | Long Time to Load Chart Data | Charts Reloading Often: 30.48 - Basic Steps to Resolve Performance Issue in Sierra Chart In the video in the second section, we explain this point as well. You can go back to a previous version with Help >> Install Previous Version until such time that you can spend the time to work through this. If you simply run Sierra Chart and you do not open any Chartbooks and you open a new Intraday chart and it takes a long time to load as compared to before, we definitely strongly suspect it is the OS performing file compression of the intraday data files in the background. Just give the OS time for that to complete. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.

Support, I understand the mechanics of what you referring to (OS file compression) and how it may impact / delay the initial processing of the chart book. However, if this is in fact the reason for such dramatic change in performance in the new versions (and I have other fellow traders experiencing and confirming same issue) can this be made a user selectable option: Compress Files or NOT? It is certainly a very drastic architectural change in behavior that is causing seriouse impact on platform usability. |

Ok one thing that maybe we have not made clear, and we thought was just generally understood, is that once the file compression is done it does not happen again. It is a one-off operation. The files should have been compressed, but there were many months with versions where Sierra Chart was not enabling compression on files. After updating to newer versions, the compression will be enabled, assuming you did not enable compression on the folder or the files yourself previously, and once the OS compresses them then everything is fine. It is a one-off operation. And better performance will be delivered with compression. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.

Support, Thank you for this detailed remark. It actually makes a lot of sense if this is a one-time operation. Perhaps, this is where the initial misunderstanding happened. I will allow ample time for platform and OS to complete the compression and retest the performance after that. Thank you. |
