llama.cpp RPC PR: Cuts 300GB Model Loading Time to 1.5 Minutes
Chuyito · reddit · 2026-08-08
A developer successfully optimized the RPC (Remote Procedure Call) model loading speed in llama.cpp on low-end hardware, reducing a 300GB model load that previously took nearly 5 minutes down to 1 minute 38 seconds—a roughly 300% performance boost.
Optimization Details:
- The patch (PR 26291) introduces a new environment variable GGMLRPCLOADTHREADS (tested with 12 threads).
- The test setup consisted of two 4060 Ti GPUs paired with DDR4/DDR5 memory in a distributed cluster.
The author joked about developing this on "potato hardware," aiming to support the "little guy" running sovereign AI on a network of 2-3 gaming PCs.
