We recently re-indexed comments to Meilisearch (a PHP process that synced data from MYSQL to Meilisearch) after a Meilisearch version upgrade. It only took about 1 hour for about 12 million documents on a 16GB/4vCPU. In your case, maybe it was a config issue? Or, an old version?

And when you'll use the v1.6 you see a much better indexation speed.
