Building a High-Performance In-Memory Cache in Go: From Basics to Production

Tue, 14 Oct 2025 09:00:00 -0500

In-memory caching is a fundamental technique for building high-performance applications. This guide walks through implementing a robust in-memory cache in Go, from basic concepts to production-ready features like automatic expiration, thread safety, and distributed capabilities.

Cache Misses Are Killing Your Application: How to Benchmark and Optimize Cache Hit Ratios

Tue, 30 Sep 2025 09:00:00 -0500

When applications start slowing down, our instinct is often to throw more hardware at the problem or spend days optimizing database queries. However, one of the most significant yet overlooked performance culprits is poor cache utilization. This article explores how cache misses silently degrade performance and provides practical strategies to benchmark and optimize your cache hit ratios.

Application-Level vs CDN-Level Caching: Strategic Implementation Guide

Thu, 21 Aug 2025 09:00:00 -0500

Effective caching is fundamental to scaling web applications. This article explores the strategic differences between application-level and CDN-level caching, with practical guidance on what to cache where and why.

Memory Optimization with Go 1.24's Weak Pointers: A Guide to Efficient Caching

Tue, 10 Jun 2025 09:00:00 -0500

Go 1.24 brings a long-awaited feature to the language: weak references. This addition opens up new possibilities for efficient memory management, particularly for applications that need to cache large amounts of data. This article explores how to implement memory-efficient caches using this new capability.

Varnish Cache Tuning: VCL, Grace, Bans and Hit Rate

Sun, 25 May 2025 16:34:42 -0500

Varnish ships with a built-in VCL that is deliberately conservative: any request with a Cookie or Authorization header goes straight to the backend, and any response with Set-Cookie is not cached. On a real site, where every browser sends analytics cookies, that means the cache does almost nothing. This guide covers the VCL changes that actually move the hit rate, how to keep serving during backend outages, how to invalidate content safely, how to size storage, and how to prove each change with varnishstat and varnishlog.
