AddTextLayer takes too much time when adding several layers

Hi! So, I tested the following code:

int X = 100;

using (var psd = new PsdImage(300, 100))
{

    for (var i = 0; i < X; i++)
    {
        var watch = Stopwatch.StartNew();
        psd.AddTextLayer($"text {i}", new Rectangle(0, 0, 10, 10));
        watch.Stop();

        Console.WriteLine(watch.ElapsedMilliseconds);
    }

    var saveWatch = Stopwatch.StartNew();
    psd.Save("myLoopingTest.psd", new PsdOptions());
    saveWatch.Stop();

    Console.WriteLine($"save: {saveWatch.ElapsedMilliseconds}");
}

and noticed it takes longer for each iteration to execute AddTextLayer, starting arround 700ms and ending about 3s (per AddTextLayer invocation).
I ran some tests… executed the same code for 20, 40, 60, 80 & 100:

Almost the exact same times, each iteration takes longer to execute than the one before.

I also found out, when invoking the Save method takes a lot of time too, for bigger numbers, it takes more that what it took to add every layer.

So, my question is: is there any way to improve these times?
My typical PSD (mostly text, with some images and figures) is taking 6 minutes each, almost all of it because of the TextLayers.
Thanks.

Interesting findings. Every text layer has his section in global text layer resource, so with the each adding this section become bigger, also the blending is needed for each layer. Aspose.PSD team can try to process rendering only on final save.
