当我尝试从我的系统 ssh 到朋友的系统时，我面临大约 5-6 秒的延迟。这是命令的详细输出：

zeus@athena:~$ ssh -v ashwin@192.168.40.211
OpenSSH_5.3p1 Debian-3ubuntu7, OpenSSL 0.9.8k 25 Mar 2009

对于以下json字符串:

{
    "abc" : 123,
    "def" : 345
}

以下架构认为它有效:

{
    "$schema": "http://json-schema.org/draft-03/schema#",
    "title": "My Schema",
    "description": "Blah",
    "type": "object",
    "patternProperties": {
        ".+": {
            "type": "number"
        }
    }
}

但是,将patternProperties更改为属性仍认为它有效.那么,这2个标签之间的区别是什么？
