According to the issue both mine and Rodney's experiments outside Hydra with cache invalidation (echo >> util/cardano-sl-util.cabal) shows ~20% speedup for all-cardano-sl when optimization is disabled.
On that basis, let's s/x%/20%/ here. input-output-hk/iohk-ops#418 takes care of passing fasterBuild = true; in the Hydra jobset only for PRs.

OK yes I have amended the commit to add that figure.
Used like this:
nix-build --arg fasterBuild true -A cardano-sl-wallet-new
