 - `apisix.router.http`: The HTTP request route. It can take the following values:
 
-  - `radixtree_uri`: (Default) Only use the `uri` as the primary index. To learn more about the support for full and deep prefix matching, check [How to use router-radixtree](../router-radixtree.md).
+  - `radixtree_uri`: Only use the `uri` as the primary index. To learn more about the support for full and deep prefix matching, check [How to use router-radixtree](../router-radixtree.md).
     - `Absolute match`: Match completely with the given `uri` (`/foo/bar`, `/foo/glo`).
     - `Prefix match`: Match with the given prefix. Use `*` to represent the given `uri` for prefix matching. For example, `/foo*` can match with `/foo/`, `/foo/a` and `/foo/b`.
     - `match priority`: First try an absolute match, if it didn't match, try prefix matching.
     - `Any filter attribute`: This allows you to specify any Nginx built-in variable as a filter, such as URL request parameters, request headers, and cookies.
   - `radixtree_uri_with_parameter`: Like `radixtree_uri` but also supports parameter match.
-  - `radixtree_host_uri`: Matches both host and URI of the request. Use `host + uri` as the primary index (based on the `radixtree` engine).
+  - `radixtree_host_uri`: (Default) Matches both host and URI of the request. Use `host + uri` as the primary index (based on the `radixtree` engine).

+:::note
+
+In version 3.2 and earlier, APISIX used `radixtree_uri` as the default Router. `radixtree_uri` has better performance than `radixtree_host_uri`, so if you have higher performance requirements and can live with the fact that `radixtree_uri` only matches uri, consider continuing to use `radixtree_uri` as the default Router.
