Fetching large file from storage takes a long time.

const response = await fetch(`/api/download?fileID=664dfbbf6b74a086ac89`);
    if (!response.ok) {
      console.error("Failed to download file");
      setIsDownloading(false);
      return;
    }

    const contentLength = response.headers.get("content-length");
    const total = parseInt(contentLength, 10);
    let loaded = 0;

    const reader = response.body.getReader();
    const stream = new ReadableStream({
      start(controller) {
        function push() {
          reader.read().then(({ done, value }) => {
            if (done) {
              controller.close();
              setDownloadCompleted(true);
              setIsDownloading(false);
              return;
            }
            loaded += value.length;
            setProgress((loaded / total) * 100);
            controller.enqueue(value);
            push();
          });
        }
        push();
      },
    });

    const newResponse = new Response(stream);
    const blob = await newResponse.blob();
    const url = window.URL.createObjectURL(blob);
    const a = document.createElement("a");
    a.href = url;
    a.download = "world.rar"; // Set the filename here
    document.body.appendChild(a);
    a.click();
    a.remove();
  };

export async function GET(req) {
  const storage = new Storage(await createAdminClient());
