pagespeed_optimize_image.exe 返回的结果比 Google Page Speed Extension 更差

pagespeed_optimize_image.exe returning worse results than Google Page Speed Extension

为什么 pagespeed_optimize_image.exe 来自 http://page-speed.googlecode.com/files/pagespeed_optimize_image.exe return 的压缩比 Google Page Speed Extension 更差?对于某些图像,甚至大约 10% 的情况更糟。 有没有办法在 Windows 7 中批量 return 与 Google Page Speed Extension 中的文件完全相同,因为 pagespeed_optimize_image.exe 是可能的?

遗憾的是,我在 Google Page Speed Service Discuss

得到了答案

(about pagespeed_optimize_image.exe)(...) it's pretty outdated. It's not related to PageSpeed Service at all, which uses a different image optimization stack. We would like to release a binary to statically optimize your images, but we just haven't been able to prioritize it. You can kind of get that today by running an Apache server locally with mod_pagespeed installed and pointing at your image directory. Then you can optimize any image you want by running 'wget' to that server. Joshua Marantz
