As a generality, does enabling SGX ( https://jbeekman.nl/blog/2015/10/sgx-hardware-first-look/ ) on intel motherboards slow down the speed of computer operations ?
SGX (Software Guard Extensions) is a feature of Intel processors that allows for secure enclave execution of code. While it provides additional security, it can also have an impact on CPU performance. The exact impact will depend on the specific workload and how it uses SGX, but in general, there can be a slight decrease in performance due to the additional overhead of securing the enclave.
Enabling SGX on a system can have a small impact on the overall performance, but it is generally minimal. The main factor that can affect system performance is the additional memory usage that SGX requires, which can impact other applications running on the system.
In general, SGX should not cause compatibility issues with applications. However, some older or poorly designed applications may not be compatible with SGX and may require updates or modifications to run properly. It is always recommended to test any critical applications before enabling SGX on a production system.
The difference in performance between SGX-enabled and non-SGX-enabled systems will vary depending on the workload and the specific SGX implementation. In general, there may be a slight decrease in performance on SGX-enabled systems due to the additional security measures, but this should not be significant for most users.
There are a few ways to optimize SGX performance, such as using larger enclaves, minimizing the use of system calls within the enclave, and using optimized memory allocation techniques. However, these optimizations may require additional development effort and may not be necessary for all applications. It is recommended to consult the SGX documentation for more specific guidance on optimizing performance for a particular use case.
