ibd is faster on the newer versions compared to the older ones because the assumevalid bypasses validation for much of the spam of the last 3 years.
v28 - block 856760 (august 2024)
v29 - block 88615...
assumevalid=0 is a tradeoff. It introduces some trust back into validation. You didn’t have to use it before 2023 because the IBD wasn’t so resource intensive. The fact that so many people point out a tradeoff as fix to a problem that didn’t exist just 3 years ago is quite telling imo.
