In this article, we are going to see performance improvement in .NET8
As per Microsoft team .NET8 going to be released in November 2023.
👉 .Net8 New features | Difference between .Net7 and .Net8
.NET 8 includes a number of performance
improvements, including:
- Tiering and
Dynamic PGO: Tiering and Dynamic PGO (profile-guided optimization)
are new features that can improve the performance of managed code by up to
20%. Tiering compiles code to multiple machine code representations, each
optimized for a different runtime scenario. Dynamic PGO uses profiling
data to optimize code at runtime.
- Vectorization: Vectorization
is a technique that allows the CPU to process multiple elements of an
array in parallel. .NET 8 includes a number of vectorization improvements,
including support for new vector types and new intrinsics.
- Branching: Branching
is a common operation in code, but it can be expensive for the CPU to
perform. .NET 8 includes a number of branching improvements, including
support for conditional move instructions and new prediction algorithms.
- Bounds Checking: Bounds
checking is a safety feature that prevents programmers from accessing
memory outside of the bounds of an array. However, bounds-checking can
also be expensive. .NET 8 includes a number of bounds checking
improvements, including support for eliding bounds checks for known-safe
operations.
- Constant Folding: Constant
folding is a technique that optimizes code by replacing compile-time constants
with their values. .NET 8 includes a number of constant folding
improvements, including support for folding more complex expressions.
- Non-GC Heap: The
.NET runtime uses a garbage collector to manage memory. However, the
garbage collector can also be expensive. .NET 8 includes a new non-GC heap
that can be used to allocate memory that does not need to be garbage
collected.
- Zeroing: .NET
8 includes a number of zeroing improvements, including support for zeroing
memory in parallel and support for zeroing memory without allocating a new
object.
- Value Types: .NET
8 includes a number of value type improvements, including support for
larger value types and support for boxing and unboxing value types more
efficiently.
- Casting: .NET
8 includes a number of casting improvements, including support for casting
between value types and reference types more efficiently.
- Peephole
Optimizations: Peephole optimizations are small optimizations that
can be performed on compiled code. .NET 8 includes a number of new
peephole optimizations.
In addition to these general performance improvements, .NET 8 also
includes a number of performance improvements for specific areas, such as:
- UTF8: .NET 8
includes a number of UTF8 performance improvements, including support for
decoding UTF8 strings in parallel and support for encoding UTF8 strings
without allocating a new object.
- ASCII: .NET
8 includes a number of ASCII performance improvements, including support
for encoding and decoding ASCII strings more efficiently.
- Base64: .NET
8 includes a number of Base64 performance improvements, including support
for encoding and decoding Base64 strings more efficiently.
- Hex: .NET 8
includes a number of Hex performance improvements, including support for
encoding and decoding Hex strings more efficiently.
- String
Formatting: .NET 8 includes a number of string formatting performance
improvements, including support for formatting strings in parallel and
support for formatting strings without allocating a new object.
- Spans: Spans
are a new type in .NET 8 that provide a more efficient way to work with
memory. .NET 8 includes a number of performance improvements for spans,
including support for copying spans more efficiently and support for
comparing spans more efficiently.
- SearchValues: SearchValues
is a new type in .NET 8 that provides a more efficient way to search for
values in a collection. .NET 8 includes a number of performance
improvements for SearchValues, including support for searching for values
in parallel and support for searching for values without allocating a new
object.
- Regex: .NET
8 includes a number of Regex performance improvements, including support
for compiling regular expressions more efficiently and support for
executing regular expressions more efficiently.
- Hashing: .NET
8 includes a number of hashing performance improvements, including support
for calculating hash codes more efficiently and support for comparing hash
codes more efficiently.
- Initialization: .NET
8 includes a number of initialization performance improvements, including
support for initializing objects more efficiently and support for
initializing arrays more efficiently.
- Analyzers: .NET
8 includes a number of new analyzers that can help you identify and fix
performance problems in your code.
Overall, .NET 8 includes a number of performance improvements that can
make your applications faster. The performance improvements in
