Unity Barracuda package GC alloc

Question

I'm using Barracuda to use ONNX models inside Unity. The input is a 96x96 Render Texture in grayscale. I want to use it in android, but I'm worried about performance, because 4.3 kb of memory is allocated for each use. Am I doing something wrong? or Barracuda is not ready? What else can you advise that achieves acceptable performance?

    public struct Prediction
    {
        public int predictedValue;
        public float[] predicted;

        public void SetPrediction(Tensor t)
        {
            predicted = t.AsFloats();
            predictedValue = Array.IndexOf(predicted, predicted.Max());
        }
    }

    public Prediction prediction;

    private void TakeScreenShot()
    {
        var inputX = new Tensor(rendTexture_forNeuro, 1, _name_of_tensor);
        ExecuteInParts(_engine, inputX);
        prediction.SetPrediction(inputX);
        inputX.Dispose();
        Receive();
    }
    private Tensor ExecuteInParts(IWorker worker, Tensor I, int syncEveryNthLayer = 5)
    {
       
        var executor = worker.StartManualSchedule(I);
        var it = 0;
        bool hasMoreWork;

        do
        {
            hasMoreWork = executor.MoveNext();
            if (++it % syncEveryNthLayer == 0)
                worker.FlushSchedule();

        } while (hasMoreWork);

        return worker.CopyOutput();
    }
