The current source code can be considered beta-quality. It passes all standard Postgres regression tests and shows good improvements in performance tests. But it lacks large-scale production verification (yet).
Other Good USB Hubs to ConsiderUgreen Revodok Pro 211 Docking Station for $64: Most laptop docking stations are bulky gadgets that often require a power source, but this one from Ugreen straddles the line between dock and hub. It has a small, braided cable running to a relatively large aluminum block. It's a bit hefty but still compact, and it packs a lot of extra power. It has three USB ports (one USB-C and two USB-A) that each reached up to 900 MB/s of data-transfer speeds in my testing. That was enough to move large amounts of 4K video footage in minutes. The only problem is that using dual monitors on a Mac is limited to only mirroring.

长江之滨，湖北宜昌，山野间、公园里、小巷中，蜡梅花迎风绽放，暗香浮动。浅黄色的小小花朵缀满枝头，或舒展盛开，或含苞待放，似点点繁星，作别冬日的萧索，带来新春的暖意。
光通信是唯一解决方案传统数据中心内部主要使用铜线进行电信号传输。铜线成本低、技术成熟，但随着带宽需求不断提升，它逐渐显露出局限。铜线传输距离较短，功耗较高。当数据中心网络速度升级到800G甚至1.6T时，铜线开始变慢。光通信成为新的解决方案。光通信的基本原理是把电信号转换为激光，通过光纤进行高速传输，然后再转回电信号。相比铜线，这种方式带宽更高、延迟更低、能耗更低，因此成为下一代数据中心网络的关键技术。
