Watch-themes shows no log and is very slow

Hello,

Thank you for Tutor! I am new to it and it seems very powerful.

I have been using tutor dev run watchthemes to build a custom theme. The rebuild appears to take up to one minute and shows no log (except the prompt Watching changes in /openedx/themes...). I have been looking into pavelib and @assets.debounce() but seems like none of this is fired.

Is there any way to shorten the build time for themes?

I am using tutor, version 10.3.0 on OSx

Many thanks
Clément
