Architecture

This section explains the core architectural decisions behind zerg: how threads are organized, how io_uring is used, how buffers flow through the system, and how connections are managed.

Reactor Pattern
Acceptor + N reactor threads, event loop design
io_uring
Linux async I/O primer and features used by zerg
Buffer Rings
Provided buffers lifecycle and zero-copy receive
Connection Lifecycle
Accept, use, close, and return to pool
Threading Model
Thread layout, memory ordering, and synchronization
