add xray-linux-amd64-avx in releases

This version is likely optimized for AMD64 architecture with support for Advanced Vector Extensions (AVX). AVX is an extension to the x86 instruction set architecture, and it introduces new instructions for vectorized floating-point and integer arithmetic operations.

thanks in advance

According to our test, there is almost no difference in performance, so not planned If you do find any performance improvement, please report to us and we will consider it again

optimized version for Dedicated and Virtual servers with AVX support

[netsupcloud]

According to our test, there is almost no difference in performance, so not planned If you do find any performance improvement, please report to us and we will consider it again

its better to be planned because you dont know when app will be optimized when the code is changed after each update and im sure you dont want test after any update. we only update our apps not compilers.

In Go, the math/rand package provides pseudorandom number generation. While the standard library doesn't have explicit AVX support for random number generation, you can use SIMD instructions with a library like github.com/minio/simdjson-go to demonstrate the concept. This library uses AVX for efficient JSON parsing

a lot of people will do pull request and you want check each one to which pull request is using a library that uses AVX ?

golang.org/x/crypto:

Cryptographic libraries often benefit from SIMD instructions for optimizing encryption and hashing algorithms. lukechampine.com/blake3:

Blake3 is a cryptographic hash function, and it's possible that it could leverage SIMD instructions for performance. github.com/cloudflare/circl:

This library is maintained by Cloudflare, and cryptographic libraries from security-focused companies may use SIMD instructions.

github.com/klauspost/compress:

Compression libraries (klauspost/compress) may use SIMD instructions for accelerating compression and decompression operations.

The text generated by AI is obviously not enough as a reason, and it cannot even answer our group's joining question correctly. Don't stick a lot of its answers anymore, it will appear that you lack basic knowledge Using SMID usually requires manual optimization, and I don't think we would have such pull requests. Most of this project is also difficult to vectorize, and the algorithm part is not maintained by us

[netsupcloud]

its not related to AI it means your answer is anywhere even if all libraries are open source you dont waste your time to check all of them you do ?

[Fangliding]

@netsupcloud I just compiled it (which will include all the dependent libraries) and tested efficiency. The conclusion is that there is no difference, and I said that there is unlikely to change in the future (and why, if you understand what I said)

[netsupcloud]

you right that compiled it with all dependent libraries but did you test all functionalities of those libraries at same time ? for example all type of encryption and decryption for shadowsocks ?

[Fangliding]

@netsupcloud I did

ok
