Hi recently when trying out Tuist in our org, I noticed that our build are slower than non-Tuist variants.

Also I noticed that this is only happening on the CI but no on local.

On local the Tuist-based builds are similar/faster than non-Tuist ones.

On checking the processes during the build execution for Tuist, I noticed that there was always an Xcode process running since 8 hours consuming a lot of CPU and memory.

Attaching the screenshot below.

Is this expected? I would assume other commands like xcodebuild, swift-frontend, xctest processes but not the Xcode one.
