HTML to PDFconversion first load extremly slow

I am using Aspose Html to PDF conversion, first time execution takes is very long, around 12 seconds and then subsequent executions takes 1 second
Everywhere in forum I see to precache the resource and use doc.UpdatePagelayout
But I am not using Aspose.word. I am using Aspose.Html and Aspose.pdf and I don see updatePagelayout for these 2 libraries, what method should I use to pre-cache ?
Also, I have Aspose license
