LGTM — simple, mechanical addition of --disable-radix-cache to 7 benchmark scripts, consistent with the established pattern in this repo (e.g., #966, #926).

Extended reasoning...

Overview\nAdds --disable-radix-cache to the SGLang server launch command in 7 AMD benchmark shell scripts (qwen3.5 bf16/fp8 on MI300X/MI325X/MI355X, and glm5 fp8 on MI355X). Each change is a one-line addition following an existing multi-line argument block.\n\n### Security risks\nNone. These are benchmark configuration scripts with no auth, crypto, or permission-sensitive logic.\n\n### Level of scrutiny\nLow. This is a straightforward config flag addition that mirrors identically structured recent merges (#966 disabling prefix caching for minimax, #926 for kimi). The change is purely additive — no logic branches, no new code paths.\n\n### Other factors\nNo bugs found by the automated system. The PR is self-contained to benchmark scripts with no production code impact. The pattern is well-established in this repo.
