Apache htaccess url重写规则

我正在为可选查询字符串使用以下htaccess url重写规则

Options +FollowSymlinks -MultiViews

RewriteEngine On

RewriteRule ^post/([0-9]+)?$ post.php?state=$1 [NC,L]
RewriteRule ^post/([0-9]+)/([a-z0-9\-]+)?$ post.php?state=$1&zone=$2 [NC,L]
RewriteRule ^post/([0-9]+)/([a-z0-9\-]+)/([a-z0-9\-]+)?$ post.php?state=$1&zone=$2&region=$3 [NC,L]
RewriteRule ^post/([0-9]+)/([a-z0-9\-]+)/([a-z0-9\-]+)/([a-z0-9\-]+)?$ post.php?state=$1&zone=$2&region=$3&sub_region=$4 [NC,L]
RewriteRule ^post/([0-9]+)/([a-z0-9\-]+)/([a-z0-9\-]+)/([a-z0-9\-]+)/([a-z0-9\-]+)?$ post.php?state=$1&zone=$2&region=$3&sub_region=$4&suburb=$5 [NC,L]
RewriteRule ^post/([0-9]+)/([a-z0-9\-]+)/([a-z0-9\-]+)/([a-z0-9\-]+)/([a-z0-9\-]+)/([a-z0-9\-]+)?$ post.php?state=$1&zone=$2&region=$3&sub_region=$4&suburb=$5&postcode=$6 [NC,L]

它太慢了，你能建议更好的方法来达到同样的效果吗。谢谢

你确定制定的规则很慢吗？@JonLin是的，这是正确的方法吗？我有数百条这样的规则，如果我有1条或超过100条，响应时间没有区别。
