Attached patch (initiated by myself and heavily enriched by Nobu) contains these sync primitives implemented in C, which makes them faster (see [1] for the benchmark's code): Rehearsal ------------------------------------------------- Q#push 1.590000 0.010000 1.600000 ( 1.605502) T#push 0.600000 0.010000 0.610000 ( 0.630444) Q#pop 4.390000 0.000000 4.390000 ( 4.389781) T#pop 0.580000 0.000000 0.580000 ( 0.578918) Q#empty? 0.480000 0.000000 0.480000 ( 0.484305) T#empty? 0.360000 0.000000 0.360000 ( 0.358559) Q#clear 1.210000 0.000000 1.210000 ( 1.214494) T#clear 0.600000 0.000000 0.600000 ( 0.588611) Q#size 0.370000 0.000000 0.370000 ( 0.365587) T#size 0.350000 0.000000 0.350000 ( 0.356985) Q#num_waiting 0.380000 0.000000 0.380000 ( 0.379199) T#num_waiting 0.370000 0.000000 0.370000 ( 0.368075) --------------------------------------- total: 11.300000sec It has already been discussed on ruby-core (see ruby-core:31100).
