For an actual large scale project? No, that's normal. That particular project was an RTL level model of a full 8C SOC. You are looking at 10s of millions of lines of actual complex and dense source code that generates object file sets in the 100s of megabytes range. Honestly, 15 minutes to link is doing pretty good. It was honestly by far the best RTL dev environment I've ever seen or heard about with QOL, avg compile times, and runtime performance that put current environments to shame.

And as I said, that was with a good rev of the linker. Every couple of months a different rev would come out that would take upwards of 4+x as long which would force us to revert back to a stable fast version.
