\n Quick Answer:<\/strong> To repair and optimize MySQL tables in WordPress, use WP-CLI<\/strong> by running wp db repair<\/code> followed by wp db optimize<\/code>. In phpMyAdmin<\/strong>, select all tables in your database and choose “Repair table”<\/em> and “Optimize table”<\/em> from the bottom action dropdown. On Linux VPS, execute mysqlcheck -u root -p --auto-repair --optimize --all-databases<\/code>.\n <\/p>\n

Why Database Tables Become Corrupted or Fragmented<\/h2>\n

High-traffic WordPress websites execute thousands of DELETE<\/code>, UPDATE<\/code>, and INSERT<\/code> queries daily.

Additionally, unexpected server shutdowns or memory exhaustion can cause index pointers to become corrupted, degrading query performance.<\/p>\n
