Splitting GPUs Across VMs Boosted Ollama Performance by ~3x

The author shares an infrastructure optimization tip: splitting 3 pooled GPUs (2x RTX PRO 4000, 1x RTX PRO 2000) from a single VM into two VMs (1 dedicated + 2 pooled). Benchmark results show Qwen2.5-72B throughput jumped from 12.2 tok/s to 33.91 tok/s, and muse-glimmer-30B improved from 14.3 tok/s to 22.61 tok/s. This change challenged the assumption that pooling doesn't impact speed much, demonstrating the benefits of resource isolation under load.
