$ openssl speed -evp aes-128-gcm | chacha20-poly1305 の結果を集めるスレ

AES-CBC が早いけど、AES-GCM/AES-CTR が遅かったり、Ryzen が爆速だったり、 ChaCha20-Poly1305 が ARM で早かったりするという噂の真相が知りたいです。コメントに適当にべたべた結果を貼ってください。

ちなみに Apple M2 おかしいくらい早いです。

CPU 情報はできれば詳細なのがほしいです。

OpenSSL のバージョンは 3.1 系の最新版でお願いします。

Here's how to disable the package that is responsible for loading the Git source control support in Visual Studio. Use at your own risk!

Create a file called devenv.pkgundef and place it next to devenv.exe in you Visual Studio's Common7\IDE (you'll need elevation for this)
Add the following entries to the file:

[$RootKey$\Packages\{7fe30a77-37f9-4cf2-83dd-96b207028e1b}]
[$RootKey$\SourceControlProviders\{11b8e6d7-c08b-4385-b321-321078cdd1f8}]

Close VS if open, open a Developer command prompt, and type devenv /updateconfiguration

HTTP Streaming (or Chunked vs Store & Forward)

The standard way of understanding the HTTP protocol is via the request reply pattern. Each HTTP transaction consists of a finitely bounded HTTP request and a finitely bounded HTTP response.

However it's also possible for both parts of an HTTP 1.1 transaction to stream their possibly infinitely bounded data. The advantages is that the sender can send data that is beyond the sender's memory limit, and the receiver can act on
