Memory usage is very high, even with low setting for MaxRecursion:

MaxRecursion = 10
|             Method |  N |     Mean | Error |        Gen 0 |       Gen 1 |      Gen 2 | Allocated |
|------------------- |--- |---------:|------:|-------------:|------------:|-----------:|----------:|
| SerializeException |  1 | 177.7 ms |    NA |    3000.0000 |   1000.0000 |          - |     30 MB |
| SerializeException | 10 | 994.5 ms |    NA |   40000.0000 |  11000.0000 |  4000.0000 |    296 MB |

MaxRecursion = 30
|             Method |  N |     Mean | Error |        Gen 0 |       Gen 1 |      Gen 2 | Allocated |
|------------------- |--- |---------:|------:|-------------:|------------:|-----------:|----------:|
| SerializeException |  1 |  3.496 s |    NA |  126000.0000 |  17000.0000 |  4000.0000 |    986 MB |
| SerializeException | 10 | 32.475 s |    NA | 1257000.0000 | 168000.0000 | 29000.0000 |  9,857 MB |

Code (as used in the unit tests):

try
{
    throw new ArgumentOutOfRangeException("index",
        new InvalidOperationException("Inner exception 1",
            new Exception("Inner Exception 2")));
}
catch (Exception ex)
{
    var ser = new YAXSerializer<Exception>(new SerializerOptions { MaxRecursion = 30 });
    _ = ser.SerializeToXDocument(ex);
}
