[Wikidata-bugs] [Maniphest] [Commented On] T104879: Define the details of the hardware we need to run WDQS

Initial estimate:

- 64G RAM at least
- SSD drive. DB size is about 70G now, if we have a spare server setup then 
anything over 100-150G should be sufficient
- Since queries are somewhat parallelized, as many cores as possible (dual 
4-core?)

What are the requirements that this hardware is needed to satisfy?

Just as a note - labs instances are incredibly slower than production hardware. 
IOPS are horrible, in particular, so if we just need 3x as an IO performance, 
we should be able to pull it off with non-ssd disks as well.

Based on the above, I think what we need is:

- 64G memory
- 300 G SSD
- 4-8 cores
