--use-api slow to deploy

[riderx]

I switched to --use-api and since then, our deployment got way slower where that before with docker.

i think all call could be done in parallel as it done with API

You can add the flag -j 3 to deploy with 3 concurrent jobs.

Main reason it's slow is that it has to wait for all local dependencies to be uploaded, rather than pulling dependencies locally for bundling with docker.
