Why is WSL2 so slow? Understand the 9P filesystem boundary, why /mnt/c/ degrades Go build times, and how to fix WSL2 performance bottlenecks on Windows.

How CPU word alignment and struct field ordering silently inject memory padding in Go. Learn field reordering to cut heap memory allocations and cache misses.

When thinking about performance, it's easy to focus on Big O notation. But in Go, the difference between the Stack and the Heap is often the difference between a service that scales and one that chokes on GC pauses. This post explores escape analysis, the "Pointer Myth", and why passing by value is often 40x faster than passing by pointer.

How Go's concurrent tri-color mark-sweep collector works under the hood. Learn pacer triggers, GOGC tuning, and zero-allocation memory pool patterns.
