Hello,

1. It's recommended to run 1 Ignite node per server, try to reduce nodes
count to 4.

2. In case you're going to use 4 nodes per server, you need to specify
backup=1 and also set excludeNeighbors on affinityFunction as described
here:
https://apacheignite.readme.io/docs/affinity-collocation#section-crash-safe-affinity
After that, data will be stored on 2 nodes (1 primary and 1 backup) and
these nodes will be on the different servers.
For 1 node per server case just set backup=1.

3. Try to set query parallelism equals to available threads on the server,
it should increase performance. (1 node per server, parallelism=16)

Regards,
Igor
