I’m here to report just that.
Here are the pg_restore times:
An average of 18m 30s. This is the slowest of all my configurations tested to date, included putting two on the 2-port SATA card (HighPoint Rocket 620 2 SATA Port PCI-Express).
The pg_dump times are:
The average is 9m 20s. Again, slower than the other test cases.
Conclusion: Having a few on the M/B is good, but putting more, slows things down.
Yes. This isn’t really a good representative example. But it’ll do for now.
