Golang garbage collection examples

Garbage Collection(GC) could play a vital effect on golang application performance. This repository demonstrates examples on how garbage collection works.

These examples could serve as a general reference for understanding golang gc phenomena. Different scenarios need explicit analysis to debug the performance related with golang gc though.

Each example has a short description inside its own directory. cmd/example1 is suggested to be the first one to check, as it describes basic garbage collection process.

1. example1 shows a basic golang garbage collection example, and explains the idea with a simple http server.
2. example2 shows a memory leak case, where garbage collection can't free the already allocated memory.
3. @todo, add example with gc optimization.

Result of this repository is based on go version: go version go1.15+ darwin/amd64

File redis.pdf was downloaded from redislabs. Here it works for a file sample.

I'm happy to get feedback if you feel these examples are helpful or not-that helpful :) You are also welcome to contribute more examples to help people to understand Golang garbage collection better.
