Downloading large file size in SharePoint 2010

Question

We have a ShaerPoint farm with upload size set to 250 MB and Download size of 5MB. Recently there were files >5MB uploaded to SharePoint. Uploading had no issues, but while downloading it is stuck(it keeps downloading without any errors or warnings but word doesnot open) and making the whole system to hang.

I tried to increase the large file chunck size to 20 MB but nothing happened. I made sure that I did an IIS reset.

Can any one give any suggestions.

Where are you setting a download limit?

Hi AneeshaR,

I have the same question with Alex. How did you set the download limitation?
As far as I know, there is no property in SharePoint, which allow us to set the download limitation. The "large-file-chunck-size" specifies the amount of data that can be read from the server running Microsoft SQL Server at one time. In other words, if "large-file-chunck-size" is 20 MB, and the file is 100 MB, then the application need to read the file from the server running Microsoft SQL Server 5 times.

Let's go back to the original question - "the System is hanging, and no errors or warnings are thrown". In order to narrow down the issue, could you please help to do the following testing?
Download a large file that is larger than 5MB from internet web

In addition, could you please help to check if there is any error in the SharePoint ULS log?

One more thing to be mentioned, if you are using Windows Explorer to download the file, please also check the FileSizeLimitInBytes from the client:

Hi Alex and Chen,

I thought that setting the Large- file- chunck -size was setting the download size from sharepoint. I guess it was my misunderstanding. I modified the registry but there is no difference. The file size I am testing is 7MB. It still says downloading from past 10 minutes. I tried downloading 15MB file from web it works fine without any issues.

Thanks.
