SDNQ compiles its helpers for static shapes, so an encode at a new prompt length or condition-image size recompiles them; on a long-running server each new length costs tens of seconds and logs the long-encode warning. With torch_skip_compile_te on (Compute Settings, next to the Triton autotune skips, off by default), hijack_encode_prompt runs the encoder under torch.compiler.set_stance("force_eager"): warm encodes are as fast as compiled ones and the denoiser keeps its compiled kernels. An encoder ticked under Compile Model keeps its compile.
