IQ quants are particularly slow on CPU at large batch sizes (what you'd see for imatrix and perplexity) Benchmark numbers I ran PPL against master and this PR to get speed and numbers on --chunks 50 for Qwen3.6-27B and Qwen3.6-35B-A3B on EPYC 9654 using 24 threads Created pure IQ1_S , IQ1_M , IQ2_X…
