Of course it is, and if this EPUB is something freely available I'll gladly do some profiling with it. Although like I said, any real improvements can only come from being smarter and not rendering the whole file on load. Because even increasing performance tenfold would still give you a good minute. And that's highly unlikely unless there's something particular that could be easily cached. But I think we're fairly close to the useful limits on that one.

Side question, have you tested how fast Plato is on your document? In theory it should be very fast because it does exactly what I described. I suspect it should not only feel much faster than Nickel, but also be faster in the artificial stress test.

(Another side question, did you long-press on the file in KOReader and open in MuPDF? I expect that should also take 10-20 minutes, mind you, but you never know.)

I gladly triple the loading times for proper kerning & ligatures. In fact I've been finding myself actually reading EPUBs since that was added, which I almost never used to. Of course we're talking only a couple of seconds here, taking loading times from <1 second to something somewhat more perceptible but fast enough.
