Explain a variety of tips that can help speed up INSERTs.

• The insert delayed should be used in scenarios where multiple clients insert a lot of data.
• Concurrent INSERTs can be applied to a table when SELECTs are running simultaneously condition being that there are no deletions taking place.
• LOAD DATA INFILE should be used as it is faster than inserts if the data is being loaded from a file.
• LOAD DATA INFILE can be executed faster by:
  1. Creating a table.
  2. Executing a FLUSH TABLES.
  3. Removing all use of indexes for the table.
  4. Inserting data into the table with LOAD DATA INFILE.
  5. Re-creating the indexes to avoid the disk seeks resulting in a well balanced index tree.
  6. And then executing a FLUSH TABLES command.
