| The overhead of policy enforcement is benchmarked in [model_b_test.go](https://github.com/casbin/casbin/blob/master/model_b_test.go). The testbed is: |
| |
| ``` |
| Intel(R) Core(TM) i7-6700HQ CPU @ 2.60GHz, 2601 Mhz, 4 Core(s), 8 Logical Processor(s) |
| ``` |
| |
| The benchmarking result of ``go test -bench=. -benchmem`` is as follows (op = an ``Enforce()`` call, ms = millisecond, KB = kilo bytes): |
| |
| Test case | Rule size | Time overhead (ms/op) | Memory overhead (KB) |
| ----|------|------|---- |
| ACL | 2 rules (2 users) | 0.015493 | 5.649 |
| RBAC | 5 rules (2 users, 1 role) | 0.021738 | 7.522 |
| RBAC (small) | 1100 rules (1000 users, 100 roles) | 0.164309 | 80.620 |
| RBAC (medium) | 11000 rules (10000 users, 1000 roles) | 2.258262 | 765.152 |
| RBAC (large) | 110000 rules (100000 users, 10000 roles) | 23.916776 | 7.606 |
| RBAC with resource roles | 6 rules (2 users, 2 roles) | 0.021146 | 7.906 |
| RBAC with domains/tenants | 6 rules (2 users, 1 role, 2 domains) | 0.032696 | 10.755 |
| ABAC | 0 rule (0 user) | 0.007510 | 2.328 |
| RESTful | 5 rules (3 users) | 0.045398 | 91.774 |
| Deny-override | 6 rules (2 users, 1 role) | 0.023281 | 8.370 |
| Priority | 9 rules (2 users, 2 roles) | 0.016389 | 5.313 |
