So, we have an application uploading files to our SharePoint site via CSOM.  and we get the message: "The request message is too large. The server does not allow messages that are larger than 2097152 bytes."  Looks like I can increase it via Powershell, but I would like to know has anybody had performance issues after increasing to say 5mb?  I've learned from experience why Microsoft has other threshold limits, I'd like to get some feedback prior to making the change.

All comments welcome.

PS- I just found a way to change code to get around this message as well using file stream (link

Hi Herschel,

There are two possible scenarios needed to be taken into consideration before increasing the MaxReceivedMessageSize:

1. Larger file will increase the risk of uploading fail due to the network and server performance;

2. There is a limit in transaction in SQL Server to restrict large file uploading to SharePoint library, when a single file is large, the performance of SQL Server will get impacted.

A documentation about software limits in SharePoint would provide more information about this:
