Hello Riccardo, not sure (really) whether that would help but i did see a massive performance boost going to convex #0.13 development version. See this thread:[Convex.jl : remarkable increase in perf in dev version (0.13.0) compared to v0.12.6, (now as fast as R/CVXR)](https://discourse.julialang.org/t/convex-jl-remarkable-increase-in-perf-in-dev-version-0-13-0-compared-to-v0-12-6-now-as-fast-as-r-cvxr/31966)

You may want to try it!

[and thanks for your issue #163 on SCS.jl, It enabled me to compile scs (the C library) in a julia-compliant way, not a piece of cake! 🤪]
