Algorithm

• shawnsmithdev/zermelo - A radix sorting library for Go.

Assembly

• mmcloughlin/avo - Generate x86 Assembly with Go.
• CAFxX/atomics - All the missing AMD64 atomic instructions.

Benchmarks

• benchstat - Benchstat computes and compares statistics about benchmarks.
• go-benchrun - Convenience wrapper around "go test" + "benchstat".

Compiling

• gcassert - Assert your Go code is inlined and bounds-check eliminated.

Concurrency

• grmon - Command line monitoring for goroutines.
• drwmutex - Distributed RWMutex in Go.

Crypto

• md5-simd - Accelerate aggregated MD5 hashing performance up to 8x for AVX512 and 4x for AVX2.

GC

• gcnotifier - Know when GC runs from inside your golang code.

Hardware

• klauspost/cpuid - Provides information about the CPU running the current program.

IO

• preallocate - File preallocation library

Math

• fastdiv - Fast division, modulus and divisibility checks in Go for divisors known only at runtime.

Network

• fasthttp - Fast HTTP package for Go. Tuned for high performance. Zero memory allocations in hot paths. Up to 10x faster than net/http.

Profiling

• profefe - Continuous profiling data collecting.
• google/pprof - pprof is a tool for visualization and analysis of profiling data.
• felixge/fgprof - a sampling Go profiler that allows you to analyze On-CPU as well as Off-CPU (e.g. I/O) time together.

Storage

• stringbank - Storing strings without GC overhead.

Testing

Articles

• The official HOW-TO on app diagnostics.
• Debugging performance issues in Go programs by Dmitry Vyukov (2014).
• Go Wiki: Compiler And Runtime Optimizations

Other

• templexxx/tsc - Get unix time (nanoseconds) in 8ns, 10x faster than stdlib.
