我的项目要求是从远程服务器中提取图像，并使用该图像创建尺寸属性为5种尺寸的产品，假设 10X10,20X20,30X30,40X40,50X50 将拉出的图像设置为产品和重定向到该产品详细信息页面
这是购买按钮的网址，点击您重定向到您网站各个页面的位置：
yoursiteurl？img = your_image_url＆amp; cap = your_caption＆amp; cat = your_category＆amp; isrc = image_source_site
这是我的代码：
$caption = isset($_GET['cap']) ? $_GET['cap'] : '';
$url_category = isset($_GET['cat']) ? $_GET['cat'] : '';
$image_source = isset($_GET['isrc']) ? $_GET['isrc'] : '';
$diff_paths = wp_upload_dir();
$saveto = $diff_paths['path'] . '/' . md5(rand(0, 1000)) . time() . '.jpg';
$image = $_GET['img'];
try {
$ch = curl_init($image);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, 1);
$raw = curl_exec($ch);
if ($raw === false) {
echo "<h3>Something went wrong, kindly try again later. Error :" . curl_error($ch) . " </h3>";
die();
} else

现在的问题是从购买按钮点击到产品详细信息页面的整个过程非常耗时大约12-20秒取决于图像大小和互联网速度，平均时间是15秒，这是非常大的。如何优化此代码，以便不必花费太多时间来获取产品详细信息页面（即查看产品页面）。
提前谢谢。
