This guide is intended to aid advanced Go users in better understanding their application costs by providing insights into the Go garbage collector. It also provides guidance on how Go users may use these insights to improve their applications' resource utilization. It does not assume any knowledge of garbage collection, but does assume familiarity with the Go programming language.

dae, means goose, is a high-performance transparent proxy solution.

To enhance traffic split performance as much as possible, dae employs the transparent proxy and traffic split suite within the Linux kernel using eBPF. As a result, dae can enable direct traffic to bypass the proxy application's forwarding, facilitating genuine direct traffic passage. Through this remarkable feat, there is minimal performance loss and negligible additional resource consumption for direct traffic.

As a successor of v2rayA, dae abandoned v2ray-core to meet the needs of users more freely.
