- allocations have halved
I already use HyperLinq in many of my projects and have been able to massively reduce memory consumption while increasing performance. This has led to us using smaller Azure instances in a variety of projects and services, reducing costs and CO2 consumption.
However, as in any bechnmark, this must be applied reasonably to the individual case in order to achieve improvement.
While allocations have not improved in .NET 8, performance has improved significantly. In some cases twice as fast.
