#8261 went a long way to solving some of the ACL performance issues. I don't think we need to create sets at all for the `find` and `isEmpty` calls. ` testAuthorizer` is 22% to 62% of the cost after this change: ``` Before: Benchmark (aclCount) (resourceCount) Mode Cnt Score Error Units AclAuthorizerBenchmark.testAclsIterator 5 5000 avgt 15 0.430 ± 0.004 ms/op AclAuthorizerBenchmark.testAclsIterator 5 10000 avgt 15 0.980 ± 0.007 ms/op AclAuthorizerBenchmark.testAclsIterator 5 50000 avgt 15 11.191 ± 0.032 ms/op AclAuthorizerBenchmark.testAclsIterator 10 5000 avgt 15 0.880 ± 0.007 ms/op AclAuthorizerBenchmark.testAclsIterator 10 10000 avgt 15 2.642 ± 0.029 ms/op AclAuthorizerBenchmark.testAclsIterator 10 50000 avgt 15 26.361 ± 0.242 ms/op AclAuthorizerBenchmark.testAclsIterator 15 5000 avgt 15 1.655 ± 0.024 ms/op AclAuthorizerBenchmark.testAclsIterator 15 10000 avgt 15 5.276 ± 0.041 ms/op AclAuthorizerBenchmark.testAclsIterator 15 50000 avgt 15 40.702 ± 0.574 ms/op AclAuthorizerBenchmark.testAuthorizer 5 5000 avgt 15 0.202 ± 0.001 ms/op AclAuthorizerBenchmark.testAuthorizer 5 10000 avgt 15 0.233 ± 0.001 ms/op AclAuthorizerBenchmark.testAuthorizer 5 50000 avgt 15 0.424 ± 0.001 ms/op AclAuthorizerBenchmark.testAuthorizer 10 5000 avgt 15 0.202 ± 0.001 ms/op AclAuthorizerBenchmark.testAuthorizer 10 10000 avgt 15 0.253 ± 0.001 ms/op AclAuthorizerBenchmark.testAuthorizer 10 50000 avgt 15 0.423 ± 0.001 ms/op AclAuthorizerBenchmark.testAuthorizer 15 5000 avgt 15 0.198 ± 0.001 ms/op AclAuthorizerBenchmark.testAuthorizer 15 10000 avgt 15 0.242 ± 0.001 ms/op AclAuthorizerBenchmark.testAuthorizer 15 50000 avgt 15 0.391 ± 0.002 ms/op JMH benchmarks done After: Benchmark (aclCount) (resourceCount) Mode Cnt Score Error Units AclAuthorizerBenchmark.testAclsIterator 5 5000 avgt 15 0.504 ± 0.164 ms/op AclAuthorizerBenchmark.testAclsIterator 5 10000 avgt 15 1.038 ± 0.271 ms/op AclAuthorizerBenchmark.testAclsIterator 5 50000 avgt 15 11.767 ± 0.028 ms/op AclAuthorizerBenchmark.testAclsIterator 10 5000 avgt 15 0.827 ± 0.016 ms/op AclAuthorizerBenchmark.testAclsIterator 10 10000 avgt 15 2.801 ± 0.027 ms/op AclAuthorizerBenchmark.testAclsIterator 10 50000 avgt 15 26.157 ± 0.191 ms/op AclAuthorizerBenchmark.testAclsIterator 15 5000 avgt 15 1.814 ± 0.053 ms/op AclAuthorizerBenchmark.testAclsIterator 15 10000 avgt 15 5.420 ± 0.065 ms/op AclAuthorizerBenchmark.testAclsIterator 15 50000 avgt 15 41.372 ± 0.659 ms/op AclAuthorizerBenchmark.testAuthorizer 5 5000 avgt 15 0.064 ± 0.001 ms/op AclAuthorizerBenchmark.testAuthorizer 5 10000 avgt 15 0.070 ± 0.001 ms/op AclAuthorizerBenchmark.testAuthorizer 5 50000 avgt 15 0.240 ± 0.001 ms/op AclAuthorizerBenchmark.testAuthorizer 10 5000 avgt 15 0.055 ± 0.001 ms/op AclAuthorizerBenchmark.testAuthorizer 10 10000 avgt 15 0.084 ± 0.001 ms/op AclAuthorizerBenchmark.testAuthorizer 10 50000 avgt 15 0.249 ± 0.001 ms/op AclAuthorizerBenchmark.testAuthorizer 15 5000 avgt 15 0.057 ± 0.001 ms/op AclAuthorizerBenchmark.testAuthorizer 15 10000 avgt 15 0.084 ± 0.001 ms/op AclAuthorizerBenchmark.testAuthorizer 15 50000 avgt 15 0.243 ± 0.001 ms/op ``` Reviewers: Ismael Juma <ismael@juma.me.uk> |
