Google Speed Test性能问题

Question

我已在Google Speed Test Tool中查看了我的网站。有些页面的速度得分很慢。如何修复未被评为“好”的所有分数。我用来测试Urls的网站是testmysite.thinkwithgoogle.com，我对移动速度只是“公平”。我正在使用htaccess文件进行URL重定向。

注意：

1）使用此网站缩小了所有CSS和HTML代码minifycode.com/html-minifier

2）使用Critical path css generator在html中添加外部css样式（在内部添加一些样式） - jonassebastianossonsson.com/criticalpathcssgenerator

3）已经在.htaccess文件中添加了以下代码。

<IfModule mod_rewrite.c>
RewriteEngine on
RewriteOptions Inherit
ReWriteCond %{HTTP:accept-encoding} (gzip.*)
ReWriteCond %{REQUEST_FILENAME} !.+\.gz$
RewriteCond %{REQUEST_FILENAME}.gz -f
RewriteRule (.+) $1.gz [QSA,L]
</IfModule>

<ifModule mod_gzip.c>
mod_gzip_on Yes
mod_gzip_dechunk Yes
mod_gzip_item_include file .(html?|txt|css|js|php|pl|gz|zip|xsl)$
mod_gzip_item_include handler ^cgi-script$
mod_gzip_item_include mime ^text/.*
mod_gzip_item_include mime ^application/x-javascript.*
mod_gzip_item_include mime ^application/javascript.*
mod_gzip_item_exclude mime ^image/.*
mod_gzip_item_exclude rspheader ^Content-Encoding:.*gzip.*
</ifModule>

<IfModule mod_deflate.c>

为了获得更高级的结果，我建议您选择Google Audit或也称为＆＃34; Google Lighthouse＆＃34;测试。在此测试期间，您将准确地看到哪些不起作用，而且大多数时候也会提出有关如何解决问题的建议。您希望实现的是性能和可访问性的绿色。

还有一个真正的helpful blog entry涵盖了lazyloading using lazysizes JS和why that matters。

如果没有指向您网站或来源本身的实际链接，很难直接向您提供反馈，并且＆＃34;如何解决＆＃34; - 但通过上述审核，你应该找到自己的方式。
