1. 支持.Net 7
2. 支持NativeAOT
3. 支持.Net Framework 4.8.1(支持ARM)
4. 支持隐藏指定列
5. 显示内存分配百分比
6. 显示进度和预计完成时间
7. 显示硬件指令集信息(如AVX2等)

        [Benchmark(Baseline = true)]
        public double RoundDefault() => Math.Round(Value);
    }
}

还有对WebAssembly支持的越来越好,输出的信息更多更全,还有显示更多的汇编代码(在测试方法中调用的其他方法显示汇编代码):

; 内联后生成的汇编代码
; CSharpBenchmarks.MathTest.RoundTest.RoundDefault()
;         public double RoundDefault() => Math.Round(Value);
;                                         ^^^^^^^^^^^^^^^^^

在看在测试方法中调用其他方法:

; net6perf.LinqTest.TakTest.Take()
; int sum = 0;
; ^^^^^^^^^^^^
; for (int i = 0; i < Times; i++)
    ; ^^^^^^^^^
    ; var array = bytes.Take(5).ToArray();
; ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
; sum += array.Length;
