Please back this claims with concrete numbers. Because I am sure it is not the case. For an instance, consider the package julia@1.6.3 built on Berlin: 1061.9+11122.3=12184.2 seconds [1] vs 1183.4+10081.1=11264.5 [2] vs 1040.7+9559.4=10600.1 [3], therefore, the worst case is: (12184.2 - 10600.1)/60 = 26.4016666667 min The variance here is obvious. And it totally depends on the value itself; the error is relative. LFS are using *exactly* what you are proposing and they document the deviation. Please follow the 2 links there [4]. I am available to share my overall timings for some packages. 1: 2: 3: 4: All the best, simon
