    Does multiple workspaces impact performance? NT8 very slow lately...

    Hello,

    I have recently discovered the use of multiple workspaces and have created quite a few:

    1. One for intraday trading. I use a short term lookback period (maximum 3 days on tick charts) .

    2. One for historical EOD analysis. Mostly daily stuff on indices.

    3. Backtesting workspace.

    4. Another backtesting workspace.

    Lately, Ninja have become painfully slow and seems to take up a lot of resources/memory. Quite often these days, the fan on my computer turns up and I can see that Ninja is taking up a lot of memory.

    Does Ninja process workspaces that are not even open? Is that why things are slow for me? Any remedies?

    Thanks in advance.

    Hello Johnny,

    Thanks for your post.

    Yes, open workspaces will use resources even if they are not the workspace being viewed. This is actually the number 1 point in our "optimizing performance tips", please review all of them here: https://ninjatrader.com/support/help...ance_tips2.htm

    We recommend that you close/save any unused workspace (Please do keep open any that you actively need though) then restart NinjaTrader and observe the TaskManager/performance monitor again.

      Hi, PaulH,

      Thanks!

      But, when I first start Ninja - is only one workspace loaded? Because these performance issues seem to happen even if I haven't opened other workspaces during that session.

        Hello Johnny,

        Thanks for your reply.

        Yes, if the workspaces are open and you exit NinjaTrader and save your workspaces, then it will open with all workspaces open but only 1 workspace will be viewed. When you left-click on workspaces in the control center you will see a list of all workspaces you have created. If there is an Icon to the left of the workspace, then the workspace is open. If the icon is Green that is the currently viewable workspace. If there is no icon then the workspace is closed. Please see the help guide here for further clarification: https://ninjatrader.com/support/help...paces_menu.htm

          Thanks a lot for clariyfing, PaulH. And sorry for bugging you guys about what is probably basic questions. I wasn't aware that I could (and should) close workspaces in that way. Hopefully, I can see some improvements after learning this.

          Thanks!

          Johnny

            Well, I closed all my workspaces and it's not helping it seems.

            I just had another program terminate because it was 'out of memory'. This is AFTER market close, so 80% of my charts are not receiving data.

            Seems like NT8 is exhausting all my memory. I have 12 GB and NT8 seems to take it all if I interpret correctly.

                Hello Johnny,

                Thanks for your reply.

                If you haven't already, please "restart NinjaTrader and observe the TaskManager/performance monitor again." with only the one workspace open.

                It is likely some other cause, such as a custom indicator, that is running away with memory

                Please write into PlatformSupport[at]NinjaTrader[dot]Com and attach your log and trace files to your e-mail so we can see if there is some other potential cause that may leave clues in these files.

                • Send the 2 compressed folders as attachments to your email.

                  PaulH,

                  It seemed to do the trick. I'll consider this solved for now. Thanks.
