IFS performance on large files deletion

See this idea on ideas.ibm.com

when deleting big files in IFS, cleanup creates huge amounts of read/write I/O in background jobs P0FBAIT00N etc.
This I/O blocks further processing if IBM i is used as FTP server and FTP processing first CDs into a directory, deletes existing files and then sends new files. Sometimes deletion needs long so FTP client will disconnect due to timeout.
The deletion in general produces a high amount of read / write I/O which kills mid-sized HDD based storage. Circumvention only by massive caching or flash based storage.
Processing of deletion should run in background and reduce amount of I/O.


Use Case:

a) storing 40TB+ of data as backup from other systems (IBM i and PC), mainly big files 5GB up to 100GB in a flat directory structure. Files will be deleted and newly created using FTP daily

b) storing big amount of small files (<300k) in a directory structure with 50.000+ files in a single directory.

c) using BRMS to dump to tape and manage retention of data.

    Thank you for taking the time to submit your request. After careful consideration, we know that we cannot deliver your requested enhancement soon, so it is being declined. However, we believe it may have future value, so we will add it to an internal list for us to keep in mind for the future.

    We are always interested in having the file system operations perform as efficiently as possible. Destroying a stream has many factors that affect the length of time it takes. As noted we already do a lot of the destroy in parallel in the P0FBAIT000x tasks. Other activity on this system as well as hardware speeds also plays a factor.

    We plan to do additional investigation on whether there is something we can do differently.

    The COMMON Europe Advisory Council (CEAC) has reviewed this requirement and recommends that IBM view this as a medium priority requirement that should be addressed.

    Background: The 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.

    To find out how CEAC help to shape the future of IBM i, see CEAC @ ibm.biz/BdYSYj and the article "The Five Hottest IBM i RFEs Of The Quarter" at ibm.biz/BdYSZT

    additional information:
    we are currently implementing (S)FTP(S) based services for some customers where they put their data on a daily base, deleting old data. Starting with about 20GB of file size, deletion needs significant amount of time on "normal" hardware. Switched to full flash based SAN the situation is better but at a high cost. Freeing pointers for IFS objecs should be run asynchronous like for deleting of QSYS objects.
    Replaced file server for 2 customers with their IBM i IFS (as they had some space TB) works like a charm for everything <4GB files. Need better performance for better argument to replace Windows or Linux file servers ;-)
