UPDATE2: PHP's memory_limit=8G is important only when rebuild is run via GUI. Using CLI via drush queue:run rest_oai_pmh_views_cache_cron works fine even if memory_limit is much lower. max_allowed_packet still needs to be at least 256M for 30.000+ items.

UPDATE: Setting up " Items to display: Display a specified number of items | x items" in a view, where x ~ small thousands (e. g. 5000 for 40.000+ items) speed up the OAI rebuild significantly. However, it still require quite a lot resources to finish (max_allowed_packet=256M, memory_limit=8G).
