perf(cuda): reuse pinned buffer completion events - #10713
1 benchmark regressed
2 warnings, 1 note
⚠️ Walltime results may be unreliableSome benchmarks used the Walltime instrument outside CodSpeed Macro Runners, which can make the results inconsistent.
⚠️ 21 benchmarks are dominated by system callsSystem calls cannot be simulated consistently and are left out of the measure. The reported value understates the real cost. Switch to the Walltime instrument to measure them.
ℹ️ 40 benchmarks have no flamegraph
The flamegraph wasn't generated: the symbols of the profiling trace could not be resolved, because no information about the language frames was collected.
