Ettore Di Giacinto d6c91b7d62 analysis: finalize PR #22569 paged-KV eval (full detail + compute-bound note)
Agent-finalized eval: builds (1-line Qwen3 reshape fix), but on GB10+32B paged is
~12% slower than contiguous and both cap at LLAMA_MAX_SEQ=256 (not OOM; 16GiB/119).
Agent argues 32B is compute-bound + plateaus by npl=128 so raising the cap won't
help - but 540 t/s << ~1900 bandwidth ceiling, so the plateau cause is unconfirmed
(attention-over-KV or CPU sampling, not matmul saturation). Next: raise the cap +
remeasure to settle it. Verdict: do not adopt #22569; paged KV not a GB10 lever.
