Today. I use three I/O scheduler in Linux and insert 5 Millions record in mysql database.

Here is the detail which i observe.

Deadline scheduler

Total time took to insert 5 Millions record in 29 min 29.25 sec

noop scheduler

Total time took to insert 5 Millions record in 30 min 57.81 sec

cfq scheduler 

Total time took to insert 5 Millions record in 33 min 6.37 sec

 

How to change scheduler to deadline. Just define in grub.conf and reboot the server
