UnverifiedCPU-based TEE solutions (such as Intel SGX) restrict protected memory (EPC) to a small capacity, causing large model workloads to frequently trigger memory swapping, with performance overhead potentially reaching several times to tens of times.80% similarUnverifiedThe available memory of Intel SGX secure enclaves was long constrained to 128MB–256MB, with later versions having expanded it to several GB.80% similarUnverifiedIntel SGX context-switch overhead can reach 10–30%, and memory encryption adds 5–15% latency.67% similar
