Earlier quoted context omitted.
How can you stand the excruciating slowness? Claude Code is running circles around codex. The most mundane tasks make it think for a minute before doing anything.
By learning to parallelize my work. This also solved my problem with slow Xcode builds.
Whenever I have more than 1 agent run Swift tests in a loop to fix things, and another one to build something, the latter will disturb the former and I need to cancel.
And then there’s a lot of work that can’t be parallelized, like complex git rebases - well you can do other things in a worktree, but good luck merging that after you‘ve changed everything in the repo. Codex is really really bad at git.
