> I see benchmarks in this PR so have you generated some numbers that show the improvement? The numbers depend on how many unbound values there are. There is no x-percent performance gain or so. I pushed it to the extremes, where the first four expressions are unbound and the fifth is bound. Then executing this a million times: ``` Benchmark Mode Cnt Score Error Units TestCoalesce.benchmarkCoalesceJena550 avgt 15 0,196 ± 0,008 s/op TestCoalesce.benchmarkCoalesceJenaCurrent avgt 15 0,027 ± 0,004 s/op ``` If there are no unbound values, it might even be a tiny bit slower because the binding might be validated twice (depending on runtime-optimization). Same test with first expression bound and ten million executions: ``` Benchmark Mode Cnt Score Error Units TestCoalesce.benchmarkCoalesceJena550 avgt 15 0,194 ± 0,005 s/op TestCoalesce.benchmarkCoalesceJenaCurrent avgt 15 0,196 ± 0,005 s/op ``` -- This is an automated message from the Apache Git Service.
