Scoring 2000 Products per Request: Performance Pitfalls in Golang

Ivan Sinitsin

Pushing Golang to 50K RPS requires abandoning idiomatic code for data-oriented design. Discover how flattening structures into contiguous arrays eliminated 600 million allocations per second.

#1 about 3 min

Identifying Go runtime overhead in high-throughput systems

Analyzing why a system with optimal metrics breaches latency SLAs due to inefficient runtime and hardware interactions.

#2 about 3 min

Architectural mismatch of enterprise design under high load

Abstract enterprise structures that work well at low scale cause massive garbage collection overhead during extreme load.

#3 about 5 min

Optimizing memory layout by replacing pointers with primitives

Replacing complex nested structures with flat primitive types eliminates transient objects and reduces pointer chasing overhead.

#4 about 4 min

Transitioning from object models to offset-based memory matrices

Flattening polymorphic structures into strict arrays of primitives provides the CPU with perfectly linear contiguous memory chunks.

#5 about 7 min

Leveraging hardware prefetchers and cache lines for speed

Shifting from random heap access to sequential data reading allows the hardware prefetcher to eliminate costly memory stalls.

#6 about 8 min

Eliminating reflection overhead with static Protobuf serialization

Generating statically typed serialization paths with vtprotobuf bypasses reflection and enables safe memory reuse via automated pools.

#7 about 6 min

Bypassing the Go runtime with custom bump allocators

Implementing an arena allocator to grab monolithic memory chunks allows instantaneous struct allocation via pointer arithmetic without runtime locks.

#8 about 4 min

Avoiding atomic operations via zero synchronization architectures

Removing atomic counters prevents cache invalidation and hardware bus locks by adopting a share-nothing execution model.
