#22246 performance issue in pants.backend.docker.utils.suggest_renames Issue created by vito-laurenza-zocdoc Describe the bug While building a docker container image which requires a large directory of many files (283488 files and 32382 directories) in the docker context, we noticed a BIG slow down in the duration of

package

goal. In our case, the

package

goal was taking 20-40 minutes to complete. Upon debugging, we discovered the source of this slowdown was due to the

pants.backend.docker.utils.suggest_renames

method. Using local pants source, we commented out the offending call in the docker build context creation, and the

package

goal completed quickly. Pants version 2.27.0.dev3 OS Found this on MacOS, but probably exists on Linux too. Additional info N/A pantsbuild/pants
