Doing some more guess work:
IO performance on a test instance of WDQS is mostly limited by writes, which should be similar to what we have in production. Grafana shows writes between 500 and 1000 IOPS.
Looking at the GC logs on wdqs-beta (for the last 24 days), it looks like heap after GC is almost never above 4Gb (we allocate 8Gb), so we can most probably save 4Gb, probably more. Since we don't expect much traffic having memory as disk cache is probably not as critical as production servers.
So my guess for the specs of a VM:
- 8 cores
- 500Gb disk, minimum 1k write IOPS (short term 300Gb would work)
- 16Gb RAM (possibly 32Gb)
