Gentles,
Does anyone have a strong feeling of performance improvement from Ontap 5 (latest) to Ontap 6? We're so conservative on upgrading Ontap that we make Orrin Hatch blush, so we've so far only put Ontap 6 on some newly built boxes (an 840 and a 760), and our in-production 760s and 840s remain running Ontap 5 for the time being.
I've noticed considerably lower CPU loads for our Ontap 6 840s vs our Ontap 5 840s, running basically the same mix of traffic.
Here's Ontap NetApp Release 6.0.1R1: Tue Dec 12 00:47:55 PST 2000

(Those are 'sysstat 10's)
Has anyone else observed similar performance improvements? I expect to have better data when we upgrade an existing heavily-trafficed box from 5 to 6 so there's a true apples-to-apples comparison...
