Justin:
The IFS itself is inherently slower than other file systems due to the object oriented nature and better security of the IFS and IBM i. A windows, Linux, or AIX instance will beat it in pure speed every time. Adding NetServer on the top makes it a bit more sluggish.
I'm not in any way suggesting that's bad, but if you have IFS file intensive operations going on, and speed counts in responsiveness to the file system, then you might want another file system.
For 90% of the operations we run on IBM i , the IFS performs very well and is not a performance bottleneck.

What exactly do you mean by "IFS" in that sentence? Do you actually mean NetServer?

Subject: Re: NFS as IFS replacement?
Good questions Patrik.
IFS is slow by comparison to other file systems, that's a known fact. It is also more securable that other file systems.
So do you gain speed by using NFS or simply trade the IFS performance for the overhead of the NFS? My guess is it's an even trade, although I have not tested it with sufficient volume to know.
NFS also implies a careful job of maintaining the UID/GID for each user across both systems. That can become tedious leading to massive security holes.
Net/Net: I would not trade IFS for NFS mount, unless it avoids duplicating
data, and the primary user of that data is on the other system. It just
does not seem to provide any real benefit, and adds complexity.

Is NFS a good replacement for having all the files in the IFS? or
what would be a good way to take the IFS out of the i but still use
it from
the
i with minimal application changes?
Question back: What's so bad in IFS to move files out to NFS? What's
the alternative (NFS server platform)? And which benefits do you expect?
Besides, moving Data from a local to a remote mountpoint is
transparent, so there should no changes be necessary.
