In this case it's both.
The IFS simply cannot compete with speed of file serving through folder shares etc. NetServer and the like. SAMBA on IBM i is a bit faster than NetServer but that brings along some security concerns and a few other items that IBM i should not have to deal with.
NFS is generally really fast but still a bit slower that the UNIX side.

Jim,
Our document management system has direct links to the IFS, no issues.
Concluding,
Is the IFS really slow, or is it the application missing direct links to the IFS which in turn make the IFS "appear" slow?

I would have bet on images on the IFS beating the remote ones any day, until I saw the empirical results.
My only guess is with the directory structure that is used by the content management the search through the directory is the source of the problem. The vendor in this case does not store a direct link to the document (which of course would eliminate significant performance issues) rather a name and the top of directory structure set aside for the specific class of documents.

Hmm. That's interesting.
We've had customers tell us that hosting files in the IFS seems to be much faster than remote hosting them.
In fact one recently moved to NFS and they are having performance issues when listing files, however NFS is normally quite fast.
I suppose mileage varies depending on various configs.
Always something. That's what keeps us all employed 😊

Richard,
I think the requirement is a combination of use cases, however the big one at this point is bringing up a PDF document in a Web Browser that is linked to the 5250 application, or the web version of the software. Our testing shows that if we host the web site on Unix, where the images are stored, and link that back to the Web site on the IBM i instance the speed of display is significantly faster, even with the additional overhead.
Straight file serving for shares is a close second use case.
