Fabio is an HTTP and TCP reverse proxy that configures itself with data from Consul. Traditional load balancers and reverse proxies need to be configured with a config file. The configuration contains the hostnames and paths the proxy is forwarding to upstream services. This process can be automated with tools like consul-template that generate config files and trigger a reload. Fabio works differently since it updates its routing table directly from the data stored in Consul as soon as...

This is a small and simple application that runs as a Windows service to record metrics several times per second. Metrics can be very different. For example, memory usage by a process or ping to a host. The application does not require a DBMS. The data is stored in an open binary format. Data viewing is possible in the form of graphs of the history of changes and in tables of current values. The configuration setting is done without editing the config files - everything is available directly in the UI application.

...With the default UDP payload size of 1400 bytes, running on Linux kernel 5.1.20, on a tg3 (so no native XDP support) gigabit NIC, sendudp does around 980 Mb/s, so practically line rate. TL;DR: in the same environment, sending a pre-generated DNS query using an ordinary UDP socket yield around 30 MiB/s whereas sending it using the senddnsqueries example program yields around 77 MiB/s. Connecting a PC with Intel Core i7-7700 CPU running Linux kernel 5.0.17 and igb driver to a laptop with Intel Core i7-5600U CPU running Linux kernel 5.0.9 with e1000e with a cat 5E gigabit ethernet cable.

Evio is a Go networking framework built around a high-performance event loop (much like libuv or libevent) but tailored for Go, bypassing the standard net package to make direct epoll/kqueue syscalls on supported OSes for maximum throughput. The library is used where ultra-low latency and high packet rates matter (for example, proxy servers or real-time packet handling). It supports TCP, UDP, and UNIX sockets, multiple address binding, and built-in load balancing across event loops (loops can run single-threaded or multi-threaded). The API is minimalist and exposes event hooks such as Data, Opened, Closed, Tick, allowing developers full control. Because of its architecture, Evio is not a drop-in replacement for standard Go's net/http or net packages; it’s aimed at network-heavy, performance-critical use-cases.
