谷歌告诉我，我有多个重定向，这就是我在.htaccess中的内容
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteCond %{SERVER_PORT} !443
RewriteCond %{SERVER_NAME} !^www\.site1\.com$
RewriteRule !/index.html https://%{SERVER_NAME}%{REQUEST_URI} [L,R]
RewriteCond %{HTTP_HOST} ^www\.site2\.com [NC]
RewriteRule ^(.*)$ https://site2.com/$1 [R=301,L]
RewriteRule ^sitemap.xml$ index.php?route=feed/google_sitemap [L]
RewriteRule ^googlebase.xml$ index.php?route=feed/google_base [L]
RewriteRule ^download/(.*) /index.php?route=error/not_found [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !.*\.(ico|gif|jpg|jpeg|png|js|css)
RewriteRule ^([^?]*) index.php?_route_=$1 [L,QSA]
我怎样才能改进它，因此它对性能的影响不大 我面临着糟糕的表现
