IBM Power Ideas Portal


This portal is to open public enhancement requests against IBM Power Systems products, including IBM i. To view all of your ideas submitted to IBM, create and manage groups of Ideas, or create an idea explicitly set to be either visible by all (public) or visible only to you and IBM (private), use the IBM Unified Ideas Portal (https://ideas.ibm.com).

Long response time on IFS shares opening ex. Word & Excel

We are using the IBM NetServer for sharing Office files like WORD and EXCEL. Opening a Word for example over a VPN connection is very slow compared to Windows file server located in the same subnet.
After looking at the traces by IBM the time difference has been isolated due to missing of SMB2 leasing and batch oplock .


Use Case:

We are using the IBM NetServer for sharing Office files like WORD and EXCEL. Opening a Word for example over a VPN connection is very slow compared to Windows file server located in the same subnet.

We only use the IBM IFS Netserver shares and not Windows Netserver, so it's very important for us to enhance this product.

    The CAAC has reviewed this requirement and recommends that IBM not implement this request. We believe this has already been solved in IBM i 7.4, which uses SMB3.

CAAC has a key role in working with IBM i development to help assess the value and impact of individual RFEs on the broader IBM i community, and has therefore reviewed your RFE.

    The CEAC has reviewed this requirement and recommends that IBM view this as a HIGH priority requirement that is important to address.

    Performance is vital in every aspect for all users. If IBM i does not perform then it might lose trust with businesses. With many people working from home, an investigation into protocol differences via VPN should be considered.

    Background: The COMMON Europe Advisory Council (CEAC) members have a broad range of experience in working with small and medium-sized IBM i customers. CEAC has a crucial role in working with IBM i development to help assess the value and impact of individual RFEs on the broader IBM i community and has therefore reviewed your RFE.

    Hi Peter

    As I understand it OPLOCK (opportunistic locking) was introduced into SMBv2.1 and IBM i Netserver uses SMBv2.0.2 in IBM i 7.2 & 7.3. Have your tried IBM i 7.4's SMBv3 support? Hopefully this would resolve your issue.

    You can check what version of SMB you are using on the client for both your IBM i and Wintel Shares using the PowerShell command:
    Get-SmbConnection | Select-Object -Property *

    I wrote an article explaining how to use the above command and understand the results, available and the link below:

    Best of luck, regards Brad
