Large validation performance

Validating a very large set of items is slow.

TestValidator<TestItem> val = new TestValidator<TestItem>();
            val.RuleFor(x => x.Value1).NotEmpty();
            val.RuleFor(x => x.Value2).NotEmpty();
            val.RuleFor(x => x.Value3).NotEmpty();
            val.RuleFor(x => x.Value4).NotEmpty();
            val.RuleFor(x => x.Value5).NotEmpty();
            val.RuleFor(x => x.Value6).NotEmpty();
            val.RuleFor(x => x.Value7).NotEmpty();
            val.RuleFor(x => x.Value8).NotEmpty();
            val.RuleFor(x => x.Value9).NotEmpty();
            val.RuleFor(x => x.Value10).NotEmpty();

            Fixture fix = new Fixture();
            List<TestItem> items = new List<TestItem>();

            for(int i=0;i<100000;i++)
            {
                items.Add(fix.Create<TestItem>());
            }

            Stopwatch sw = new Stopwatch();
            sw.Start();

            for (int i = 0; i < items.Count; i++)
            {
                val.Validate(items[i]);
            }

            sw.Stop();
            Debug.WriteLine(sw.Elapsed.TotalMilliseconds);

Validate all items take 90 seconds…

There is any tips to optimize performance ?

3 seconds still seems slow for such a simple validation

Yes. I test the case with a simple console app and there is the same result. In debug mode 90 seconds in release mode 3 seconds. I continue to investigate…
