The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.
If you know of an easy to use, open source, search engine ... please contact support@midrange.com.
If I do a CRTLF and set the unit parameter, instead of the CREATE INDEX, will this be a valid test.

Very true David. And in a mixed unit shop you have to run certain operations on the object after changing the UNIT in order for it to actually move all parts of the object to SSD. All documented somewhere.

Does this increased thread support extend to DDS files created with

We have a lot of vendor supplied files...
Keep in mind the UNIT parameter is just the 'Preferred storage unit'.
There's no guarantee that the data will be stored on a SSD if there aren't
any available.
It's entirely possible to specify UNIT(*SSD) on objects when you don't
actually have any SSD's installed.
