In which of these areas are you experiencing a problem?

Theme

Expected behavior

I expect shopify theme push -d in @shopify/cli@3.64.0 should complete in no more than 5s, should be same as @shopify/cli@3.47.5.

Actual behavior

I found that v3.56.x ~ v3.64.0 (the latest version at this moment) is very slow when uploading the theme files using shopify theme push -d.

• Taking about 15s ~ 2minutes for a simple theme in development store that initially created by shopify.
• Taking serveral minutes to upload my formal theme(not a big project) in my prod store.

I tested cli 3.47.x ~ 3.53.x, shopify theme push -d is far more faster than the new versions, taking no more than 5s.

Intuitively, the versions with the colorful upload progress bar are slow, and the versions with the old style upload progress bar are faster.

• new UI
• old UI

Below is a more detail table

As you can see by the table above, my new PC doesn't run the old version of the CLI properly and I have to use the new version, so I'm desperate to find a solution to the slow uploads.
