"WebApr 26, 2024 · 13 seconds is the first solve. ~0 seconds is the second solve. so that leaves 6 seconds to start Julia. We're working on improving the using JuMP and our "time-to-first-solve" issue, but there are a few things you can do in the meantime. Don't run scripts via julia file.jl. Open Julia once and use the REPL. That avoids the 6sec overhead. " - Cvxpy vs scipy
