DDF Performance - Version 3 - but still highly relevant

I've just submitted a set of slides to Slideshare. They're not mine, they're not new, they're not even in a modern format. But they are a very good presentation worth preserving...
In 1993 Curt Cotner presented a set of slides on the new DDF Inactive Thread support in Version 3 of DB2. It's still highly relevant and this support was the base on which the Version 4 WLM classification line item was built.
You can find the slides here.
I'd also recommend you went on to read John Arwe's paper on Preemptible-Class SRBs.
