Hello. We recently upgraded from version 3.0.48.2 to version 4.0.12.2. We are experiencing performance issues with HtmlToPdf.ConvertHtml with the new version that we did not have with the old version.
To give you an example, I can pass "<html><head></head><body></body></html>" to the new version and it will take 14 seconds to convert. I pass this same string to the old version and it completes in under a second.
Any thoughts?
Thank you!

I did a little more testing an narrowed this issue down to setting the 'NoScript' option.
Consider this code:
Console.ReadLine();
string html = "<html><head></head><body></body></html>";
PdfDocument doc = new PdfDocument();
doc.Info.Author = "x";
doc.Info.Subject = "x";
doc.Info.Title = "x";
doc.Info.Keywords = "x";
doc.Info.Creator = "x";
doc.Info.Producer = "x";
doc.Info.CreationDate = DateTime.Now;
doc.Info.ModifiedDate = DateTime.Now;
HtmlToPdf.Options.BaseUrl = "http\\www.something.com";
HtmlToPdf.Options.OutputArea = new RectangleF(0.5F, 0.4F, 7.5F, 10.6F);
HtmlToPdf.Options.NoLink = true;
HtmlToPdf.Options.NoScript = true;
while (quit.ToUpper() != "X")
{
Console.WriteLine(string.Format("calling html to pdf: {0}", DateTime.Now));
HtmlToPdf.ConvertHtml(html, doc);
Console.WriteLine(string.Format("html to pdf done: {0}", DateTime.Now));
quit = Console.ReadLine();
}
If I run this without setting HtmlToPdf.Options.NoScript , it runs just fine with either version of EO.Pdf. If I keep this setting, the 4.0.12.2 version takes a 14 seconds or so to render, while the 3.0.48.2 version renders just fine.
Thanks!

Thank you! That does fix the issue. I apologize for not looking for a newer release and trying that first!
