Xamarin.Macサポート終了に伴い.NET8にフレームワークを移行しました。現在動作確認をしているのですが、ローカルストレージからNASへのファイルコピー処理中に速度がどんどん低下し、最終的にはOSのUIが固まって落ちてしまいます。以下クラッシュレポートです。

** Stackshot Succeeded ** Bytes Traced 320483 (Uncompressed 801440) **

ローカルからローカル、またはローカルから外付けのSSDへのファイルコピーであれば速度低下やUIがフリーズする現象は起きず、NASに対して実行した時のみ発生します。 書き込み量に関してはばらつきがあるのですが、概ね20GB以上をコピーしたあたりから速度低下が発生します。アクティビティモニターを確認していると「kernel_task」のCPU使用率が異常に高くなっている事が確認できています。調査を続けていくとおそらくファイルコピーの処理が良くないのではと考えているのですが原因が特定できずに困っております。ご教示いただけますと幸いです。

以下コピー処理のコードです。

public void CopyFile(FileInfo source, FileInfo destination, IProgress<CopyProgress> progress,
            CancellationToken token)
        {
            var InputBufferSize = 1 << 20
            if (source == null)
                throw new ArgumentNullException(nameof(source), "Could not locate the source file.");
            if (destination == null)
                throw new ArgumentNullException(nameof(destination), "Could not locate the destination file.");

            destination.Directory?.Create();
            var bytesWrote = 0L;
            using (var srcFs = File.OpenRead(source.FullName))
            using (var dstFs = File.OpenWrite(destination.FullName))
            {
                var buffer = new byte[InputBufferSize];
                var bytesRead = srcFs.Read(buffer, 0, buffer.Length);
                while (bytesRead > 0)
                {
                    dstFs.Write(buffer, 0, bytesRead);
                    bytesWrote += bytesRead;
                    progress?.Report(new CopyProgress
                    {
                        BytesProcessed = bytesWrote,
                        BytesTransferred = bytesRead
                    });
                    bytesRead = srcFs.Read(buffer, 0, buffer.Length);
                    token.ThrowIfCancellationRequested();
                }
            }
        }
