You can reindex Magento data faster manually via SSH.
For this, you need to have an SSH access to your web hosting account.
After accessing your hosting account via SSH, go to your Magento installation directory (e.g. public_html/store) and run the below command, based on the version of your Magento application:
Magento 1.9.x and Older:
/usr/local/php56/bin/php-cli -f shell/indexer.php reindexall
Magento 2.x and Newer:
/usr/local/php72/bin/php-cli bin/magento indexer:reindex
With this command, the data will be reindexed by all indexers.
