UltraNumericEditor ctor performance issue

I'm still fighting with slow UltraGrig performance. I've found that the UltraNumericEditor constructor has a bad performance, see the picture below. Is there a fix or work around for this issue, please? Thanks.

Hello and thank you for contacting Infragistics. What triggers the issue? I will require some more info, a sample and a profiling session.

Please clarify how you are using/embedding the UltraNumericEditor in the UltraGrid.

            const int iterations = 100000;

            GC.Collect();

            var stopwatch = Stopwatch.StartNew();

            for (var i = 0; i < iterations; i++)
            {
                var e = new UltraNumericEditor()
                {
                    NumericType = NumericType.Decimal
                };
            }

            stopwatch.Stop();

            var editorMs = stopwatch.ElapsedMilliseconds;
            var editorTicks = stopwatch.ElapsedTicks;
            stopwatch.Reset();

            GC.Collect();

            stopwatch.Start();

            for (var i = 0; i < iterations; i++)
            {
                var o = new object();
            }

            stopwatch.Stop();

            Debug.WriteLine($"e: {editorMs}/{editorTicks}, o: {stopwatch.ElapsedMilliseconds}/{stopwatch.ElapsedTicks}");

e: 4137/41372856, o: 0/5911

Update: Seems, the performance degradation depends on the number of instances created.

const int iterations = 100000;

var list = new List<UltraNumericEditor>();
for (var i = 0; i < 30000; i++)
{
	var ee = new UltraNumericEditor()
	{
		NumericType = NumericType.Decimal
	};
	list.Add(ee);
}


GC.Collect();

var stopwatch = Stopwatch.StartNew();

for (var i = 0; i < iterations; i++)
{
	var ee = new UltraNumericEditor()
	{
		NumericType = NumericType.Decimal
	};
}

stopwatch.Stop();

var editorMs = stopwatch.ElapsedMilliseconds;
var editorTicks = stopwatch.ElapsedTicks;
stopwatch.Reset();

GC.Collect();

stopwatch.Start();

for (var i = 0; i < iterations; i++)
{
	var o = new object();
}

stopwatch.Stop();

Debug.WriteLine($"e: {editorMs}/{editorTicks}, o: {stopwatch.ElapsedMilliseconds}/{stopwatch.ElapsedTicks}");

e: 30170/301703785, o: 0/3215
