We had to cache this page as it was timing out on big sites.
The translation has basically two steps:
- Detect post original language
- Translate to every other language
At the beginning, your site will mostly be stuck doing step 1, which we initially showed in this translation progress page but have since removed because feedback said it was “too much information”.
That said, this is good feedback. The progress page cache and lack of information of locale detection is making the experience here awful at the beginning of the process.
Last thing, we set the backfill rate very conservatively, you may want to increase it according to your budget.
