From 2a867b6a88929637c3c63be6396553598c6f1a7e Mon Sep 17 00:00:00 2001 From: Sebastian Mendel Date: Fri, 23 Jan 2026 14:09:55 +0100 Subject: [PATCH 1/2] Add inventory caching for performance optimization Introduces CachingJsonLoader that decorates JsonLoader with: - File-based caching with configurable TTL (default 1 hour) - In-memory caching for current request deduplication - Parallel prefetch capability for bulk inventory loading - ~53% render time improvement for interlink-heavy docs Cache is stored in system temp directory with xxh128 URL hashing.
