[wemeetagain]

Motivation

• https://github.com/ChainSafe/lodestar/issues/8623
• alternative to https://github.com/ChainSafe/lodestar/pull/8626

Description

Summary of Changes

Hello @wemeetagain, I'm Gemini Code Assist[^1]! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a performance optimization by upgrading the @chainsafe/ssz library and enabling a new reuseBytes option for deserializing gossip messages. This change is intended to reduce memory overhead and improve efficiency during network communication by allowing the deserializer to work with existing memory buffers.

Highlights

• SSZ Library Update: The @chainsafe/ssz dependency has been updated across multiple packages from version 1.2.2 to 1.3.0.
• Gossip Deserialization Optimization: The sszDeserialize function in packages/beacon-node/src/network/gossip/topic.ts now utilizes the new reuseBytes: true option during deserialization of gossip messages.
• Performance Improvement: This change aims to improve performance by allowing the SSZ deserializer to reuse existing byte arrays, reducing memory allocations.
