CLI is so/too slow

I'm going to second this. I was very excited to use op inject for some property files that we currently have stored in an inconvenient way. However it appears that performance is linear in the number of references in the file. We have almost 400 in one file and it takes a full minute to inject. Here it doesn't seem to matter if I use --cache or not. I would really like to use this for our production secrets, but at the moment I'll hold off until injection only takes a few seconds.
