Hi guys,

I am doing some test with super-nodes on orientdb 1.6.4.
Basically I am trying to create a super-node with 3 million edges.
The insert performance becomes really slow after the first 50K edges (I am 
using the OIntentMassiveInsert committing every 1000 records).
Moreover if I try select the super-node record from console the server 
throws an OOM error.

Any idea?

Thanks,
Fabrizio
