ViggoC opened a new issue, #44642: URL: https://github.com/apache/arrow/issues/44642
### Describe the enhancement requested The performance of VariableWidthViewVector is much slower than VariableWidthVector in some cases. `setZero` for overwriting is the bottleneck. ``` VariableWidthViewVectorBenchmarks.setSafeFromArray 1 avgt 5 0.088 ± 0.002 ms/op VariableWidthViewVectorBenchmarks.setSafeFromArray 2 avgt 5 0.095 ± 0.020 ms/op VariableWidthViewVectorBenchmarks.setSafeFromArray 10 avgt 5 0.091 ± 0.012 ms/op VariableWidthViewVectorBenchmarks.setSafeFromArray 40 avgt 5 0.087 ± 0.001 ms/op VariableWidthVectorBenchmarks.setSafeFromArray 1 avgt 5 0.010 ± 0.001 ms/op VariableWidthVectorBenchmarks.setSafeFromArray 2 avgt 5 0.013 ± 0.001 ms/op VariableWidthVectorBenchmarks.setSafeFromArray 10 avgt 5 0.032 ± 0.001 ms/op VariableWidthVectorBenchmarks.setSafeFromArray 40 avgt 5 0.105 ± 0.002 ms/op ```  See code of benchmark in https://github.com/apache/arrow/pull/44634. ### Component(s) Java -- This is an automated message from the Apache Git Service.
