Hello Rob,

IBM i, in general is not the best server for serving up shares. Often it has nothing to do with the disk drives and controllers but more to do with the OS. Years ago we took a system which had abysmally slow time serving up shares and added an IPCS card (or whatever the model du jour was called). It used the same drives, controllers, etc but did a much better time serving up shares.

Thanks for reassuring what I perceived over time, also. And yes, pure block level access (as in "disk image file" is much better, but quite still not adequate). But then, I don't care too much, because I know the platform's strengths lay elsewhere.

But IFS in general is a weak spot. Mounting NFS exports from my 150 to Linux is painfully slow, up to the point of syslog spam about timeouts, just when accessing files sized in the single digit kilobyte range.

Granted, it's been a few releases since such cards were supported, and IFS performance has been mentioned as something IBM was trying to improve in some of those releases since.

Honestly, they have to when they want to stay competitive while transforming IBM i to some kind of AIX/OpenSource Clone.

I forget: what release we were on at the time, when *TYPE2 directories came out and so on.

I remember to have seen this on my 150 with V4R5, already.

:wq! PoC
