Similar picture here as it happens. No Java stack and no intention of using ABAP Classes or XML containers yet. But obviously the Workflow engine has been re-written with these things in mind so yes it's proving hard to comapre in terms of runtime like-for-like.<BR><BR>
One thing is absolutely clear though: ECC 6 is a total memory hog by comparison. SAP have advised us to add on 50% more workspace needed to keep the same traffic flowing just to be sure and they don't seem to be far off the mark.<BR>
<BR>
We're running full scale volume tests with a Pre-Production environment starting this weekend (rehersal for the real upgrade) so I'll have more data to hand next week. I'm keeping my eye on some of our heavy workflow steps to see how long they take in the new environment. The only drawback is that we won't have exactly the same hardware to play with (4 app servers instead of 16) but at least I should be able to compare the same Workflow instances and spot any odd timing differences between 4.6c and ECC 6.<BR>
<BR>
I have taken the precaution to change all of our Workflow definitions to continue to use the 'old' BOR Object-based container (Structure Persistence) for now. You may want to do the same as the default setting (Compatibility) will seek to switch to the new XML container when the release version of the Workflow Header is later than 4.6c. But that's up to you of course :)<BR>
<BR>
I've not heard the '30% slower' figure by the way. My gut feel is that things are slightly slower all round, particularly deadlines, but I've not noticed that much of a delay, yet.<BR>
