Hi Neto,
In a great piece of timing my new experimental SSD arrived (WD Black 500
G 3D NAND MVME) [1]. Doing some runs of query 9:
- default config: 7 minutes
- work_mem=1G, max_parallel_workers_per_gather=4: 3-4 minutes
Increasing either of these much more got me OOM errors (16 G of ram).
Anyway, enjoy your benchmarking!
Cheers
Mark
[1] Yeah - I know this is a 'do not use me in production' type of SSD.
It is however fine for prototyping and DSS scenario run type use.

Mark,
This query 9 is very hard, see my results for other queries (attached
- test with secondary index and without secondary index - only primary
keys), the SSD always wins in performance.
Only for this query that he was the loser, so I put this topic in the list.
Today I will not be able to check your test information in more
detail, but I will return with more information soon.
Best Regards
Neto
