Performance improvements to AWS SDK for .NET

We recently fixed a performance issue which affects versions of the SDK that target .NET Framework 4.5. This issue is present in SDK versions 2.0.0.0 – 2.2.4.0 and only affects synchronous API calls.

This issue results in the usage of additional threads while using the synchronous APIs. In some specific environments—for example, with ASP.NET applications running on single core machines—we have seen this issue introduce additional latency intermittently for SDK calls. SDK versions 2.3.x.x and onwards contain the fix for this issue.
