hi @syedelec I made the performance comparison between C TAs and Rust TAs, on `random` and `aes`: ``` # time ./random-rs Invoking TA to generate random UUID... Invoking done! Generate random UUID: 918585d0-6be4-4d7-e09dcb5e4387c79b Success real 0m 0.46s user 0m 0.07s sys 0m 0.24s # time optee_example_random Invoking TA to generate random UUID... TA generated UUID value = 0xad36b1d0f8134f8ae2cb4a14bf11813d real 0m 0.34s user 0m 0.06s sys 0m 0.19s ``` ``` # time ./aes-rs Prepare encode operation Load key in TA Reset ciphering operation in TA (provides the initial vector) Encode buffer from TA Prepare decode operation Load key in TA Reset ciphering operation in TA (provides the initial vector) Decode buffer from TA Clear text and decoded text match real 0m 0.56s user 0m 0.11s sys 0m 0.28s # time optee_example_aes Prepare session with the TA Prepare encode operation Load key in TA Reset ciphering operation in TA (provides the initial vector) Encode buffer from TA Prepare decode operation Load key in TA Reset ciphering operation in TA (provides the initial vector) Decode buffer from TA Clear text and decoded text match real 0m 0.39s user 0m 0.07s sys 0m 0.21s ``` Yes, Rust TAs has lower performance (about 35%) than C TAs on my environment (QEMUv8 & OP-TEE 3.17.0). For performance optimization you can find some guidance on the [Cargo documentation](https://doc.rust-lang.org/cargo/reference/profiles.html). Possible workarounds are using higher `opt-level`, disabling some runtime checks, etc. -- This is an automated message from the Apache Git Service.
