Memory Leak on Windows 7

Hello, I am experiencing what I believe is a memory leak in Sierra running on Windows 7 in a VirtualBox environment. Background: Over the weekend I rebuilt my Windows 10 system with Linux and am using VirtualBox to run a Windows 7 64bit system for Sierra. Windows 7 was given 4vCPU and 8GB memory. On Windows 10 I was running 1875 and on the Windows 7, I installed the latest 1880 version. Since then I have had my memory usage slowly increase, more so when the market data volume increases or maybe just when I am more actively using it. On initial reboot and load of Sierra, Sierra claims to use about 250MB and total system usage is about 1.5GB. Last night, I looked at my total system memory usage after running all day and it was at 4.3GB, but Sierra was only showing 270MB. I then closed Sierra and the memory went from 4.3GB to 1.5GB. When I started Sierra again, I noticed the memory jumping around between 1.8GB and 3.8GB. I never noticed this on my Windows 10 system. After the chartbooks were opened and data downloaded, it returned to 1.8GB. This morning (7am EST), I looked at the system and it was at 2.3GB. About an hour later (8:30am EST now) after I went through and looked at the charts for the morning, it is at 3.3GB. Nothing else is on this computer except for the Gain Capital OEC platform. I don't know if this is an issue with 1880, Windows 7 or it running under VirtualBox, but would like your input and thoughts, maybe some things to try to isolate further? I will try to roll back to 1875 now and see if I continue to have the problem throughout the day. When I closed Sierra to roll back my memory usage went from 3.3GB to 1.3GB. After rebooting and starting 1875, my memory went from 900MB to 2.8GB. I will play around with closing some chartbooks to see if one of them may be corrupted and update the post later. Kind Regards, Kevin |

I closed all of my chartbooks one at a time and gained 1GB back closing the NQ chartbook. I then excluded that from loading on startup, thinking it was corrupted, but still went from 1.6GB to 2.7GB after running. Outside of Sierra, the Windows 7 is functioning as expected.

There is no memory leak in Sierra Chart at all. What you are seeing is most likely caching of the intraday data file data by the operating system.

Is there anyway to disable the caching of the intraday data on Windows 7? I didn't experience this at all on Windows 10 the last 2 years nor on Windows 7 previously, but they were physical installs, not virtual. Thanks. |

We are not aware of a setting for this.

We are not aware of a setting for this. But what it is doing is not really a bad thing. Just make sure you have enough memory. We would think it would be a good that the data is in memory and can be quickly accessed.
