Generating HTML, letting TCPDF parse that HTML and rejiggle it into Postscript instructions, then write this Postscript is of course going to be way slower than directly writing the Postscript to begin with. Use the regular Ln Cell Write etc. methods to directly generate the PDF if you want maximum performance. Yes, it's somewhat more complicated than writing HTML, but that's because they're different things.
And the slow part is translating between those different things.
