  • Looking at the code for the AWS SDK for .NET, I suspect the culprit of the slow initialization is the endpoints.js file. This 700+ KB megalodon JSON file is parsed every time the AWS SDK is initialized. Since this happens in the AWS Core assembly, this penalty is incurred by all AWS service clients.

  • WorkOS

    The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.
