Your ML inference isn't slow because of compute — it's memory-bound. Here's how to diagnose it with profilers and fix it with kernel fusion and quantization.
Your GPU sits at 15% utilization and bigger batches don't help? Here's how to diagnose whether you're compute, memory, or overhead bound — and fix it.
