我正在做一个功能，压缩图像列表并下载它们。我遇到了一个问题，下载花了很长时间。如何提高下载速度？

public function downloadImages(Request $request)
{
    $zipFileName = $this->service->downloadImages($request);

    return response()->download($zipFileName, null, ['Content-Type: application/octet-stream','Content-Length: '. filesize($zipFileName)])->deleteFileAfterSend(true);
}

服务

public function downloadImages(Request $request)
{
    $imageUrls = $request->get('images');
    $type = $request->get('type') ?? 'images';

    $zip = new ZipArchive();
    $zipFileName = $type . '.zip';

    $zip = new ZipArchive();

    if ($zip->open($zipFileName, ZipArchive::CREATE | ZipArchive::OVERWRITE) === true) {
        foreach ($imageUrls as $imageUrl) {
            $imageContent = file_get_contents($imageUrl);
            $filename = basename($imageUrl);
            $zip->addFromString($filename, $imageContent);
        }
        $zip->close();

        return $zipFileName;
    }

    return $zipFileName;
}

在客户端，我打电话 AJAX

function downloadImages(eleClass) {
    $("div.spanner").addClass("show");
    $("div.overlay").addClass("show");
    const imageLinks = [];
    $('ul.'+ eleClass +' li img').each(function() {
        var imageLink = $(this).attr('src');
        imageLinks.push(imageLink);
    });
    if (imageLinks.length == 0) {
        $("div.spanner").removeClass("show");
        $("div.overlay").removeClass("show");

        return;
    }

    $.ajax({
      url: '/api/download-images',
      method: 'POST',
      data: { images: imageLinks },
      xhrFields: {
        responseType: 'blob' // Set the response type to 'blob'
      },
      success: function (data, status, xhr) {
        // Handle success, e.g., show a success message
        console.log('Images downloaded successfully.');
        // Create a temporary anchor element
        var downloadLink = document.createElement('a');
        downloadLink.href = window.URL.createObjectURL(data); // Create a Blob URL for the response
        downloadLink.download = eleClass + '.zip'; // Set the desired file name

        // Programmatically trigger the download
        downloadLink.click();
        $("div.spanner").removeClass("show");
        $("div.overlay").removeClass("show");
      },
      error: function (xhr, status, error) {
        // Handle error, e.g., display an error message
        console.error('Error downloading images:', error);
        $("div.spanner").removeClass("show");
        $("div.overlay").removeClass("show");
      }
   });
}

我在浏览器上看了，花了很长时间才“内容下载”

我正在寻找一个解决方案，以提高文件下载速度。或者另一种压缩图像链接和下载列表的解决方案
