tplink 可能有渠道控价,最划算可能不再京东这种旗舰店。 我在咸鱼买到最低,仅限做完调研的型号。
我对吃不准有没有坑的电子产品 ,京东自营优选 ,不喜欢请他上门拿走,不用沟通,点两下就行了。
安徽的一个牌子,兮克 ,网站有点不像技术公司。
2014 新固件刚支持 LACP 聚合,虽然我也没用到。
还有个 hasivo 牌子我看评论有人给它混刷了兮克 的固件,估计两家都是公版方案。
tplink 早期的 5 口万兆 、 8 口 2.5G 都非常的热,
我前者已有 RMA 过,换个 220v 插座的间隔就莫名挂了。
它这么热我不敢放在封闭空间,没有遇到速度问题
我刚换别的牌子的带管理的型号,
新版的 8 口 2.5g 含 10g-sfp 不热,
方便自己查问题时知道端口速率 和错误包,
限制广播速率等,还是有点可玩性的,
比以前还便宜了
原配充电器考虑了最大负载+充电负载
不是那种使劲折腾的人,用完电池跑去插电跑编译。
即便是 macbook 原配 140w 的,你 80%满电用 pd 65w 也不会有太多感觉。
联机试过 d3 ,都在同一个家庭里战网组队,没问题
分手厨房当时也玩过的,可以
我也有体会最近几个月联通宽带基本不可用 icloud 服务,规律像是 AS12222 受阻 。连信任设备列表都刷不出来。
这些问题只有在宽带上出现,但联通的蜂窝网络是工作的。
网络挂载的延迟,恐怕微信不给你优化 , 后果可能非常卡 UI
总结就是机场的连接质量没关系,就是 rules 需要维护
Windows iperf3 和它自己的 WSL ubutnu iperf3 本机自己和自己玩 ,
观察到的是个新子网 IP ,系统新增了个适配器 [以太网适配器 vEthernet (WSL)] :

就不想动脑子了,你的预期-b 0
-b, --bitrate #[KMG][/#] target bitrate in bits/sec (0 for unlimited)
(default 1 Mbit/sec for UDP, unlimited for TCP)
(optional slash and packet count for burst mode)
是不丢包?
早期 usb 2.0 优盘没啥温度, 升级到 3.0 后主流产品都是越小越烫,
这应该是预期的吧。
我手上的 usb3 、thunderbolt3 的 nvme 盒子,在半小时后反而温度并没有差太多,手感都是略烫手
他们都有导热相变材料做外壳和芯片的连接。
