CodeProject.ObjectPool by: Ofir Makmal <ofir.makmal@gmail.com> Alessio Parma <alessio.parma@gmail.com>

A generic, concurrent, portable and flexible Object Pool for .NET. It is completely based on the Code Project article of Ofir Makmal (http://goo.gl/4qig6T). Library is production ready and it is successfully working in real life systems. Original source code has been modified, in order to introduce a Parameterized Object Pool, already drafted by Ofir Makmal in the comments of the article. Moreover, a few unit tests have been added, in order to improve code reliability, and a lot of other small changes have also been applied. Of course, all modified source code is freely available at the project URL of this package. Many thanks to Ofir Makmal for his great work.

CommunityToolkit.HighPerformance by: Microsoft

This package includes high performance .NET helpers such as: - Memory2D<T> and Span2D<T>: two types providing fast and allocation-free abstraction over 2D memory areas. - ArrayPoolBufferWriter<T>: an IBufferWriter<T> implementation using pooled arrays, which also supports IMemoryOwner<T>. - MemoryBufferWriter<T>: an IBufferWriter<T>: implementation that can wrap external Memory<T>: instances. - MemoryOwner<T>: an IMemoryOwner<T> implementation with an embedded length and a fast Span<T> accessor. - SpanOwner<T>: a stack-only type with the ability to rent a buffer of a specified length and getting a Span<T> from it. - StringPool: a configurable pool for string instances that be used to minimize allocations when creating multiple strings from char buffers. - String, array, Memory<T>, Span<T> extensions and more, all focused on high performance. - HashCode<T>: a SIMD-enabled extension of HashCode to quickly process sequences of values. - BitHelper: a class with helper methods to perform bit operations on numeric types. - ParallelHelper: helpers to work with parallel code in a highly optimized manner. - Box<T>: a type mapping boxed value types and exposing some utility and high performance methods. - Ref<T>: a stack-only struct that can store a reference to a value of a specified type. - NullableRef<T>: a stack-only struct similar to Ref<T>, which also supports nullable references.
