Performance
Indexing
Indexing time
This test measured the time which is needed to index x-times the content of Ecore.ecore. (Containing 393 instances of EObject and 520 references)

1000 | 2000 | 3000 |
| SAP | 15,4 s | 29,9 s | 45,3 s |
| Itemis | 14,6 s | 28,4 s | 43,5 s |
Memory consumption
This test measured the in memory size of the index. In the SAP case, paging was disabled

1000 | 2000 | 3000 |
| SAP | 136 million bytes | 278 million bytes | 408 million bytes |
| Itemis | 169 million bytes | 340 million bytes | 508 million bytes |
Query response time
Query All EObject and all EReferences
| |
1000 | 2000 | 3000 |
| SAP | 0,3 s | 0,45 s | 0,65 s |
| Itemis | 1,4 s | 2,2 s | 3,3 s |
