MySql is much slower on docker than setting it up on bare VPS

What could I do to solve this problem? My backend call to sql just to do a pagination of 1000 data delay up to 5.6 second. This is insane for production.

Hi there @oudamsith,

I’ve seen similar problems in the past, one solution worked quite well for me as described here:

  • First disable writing barrier for the ext4 fs:
  • sudo nano /etc/fstab
  • Your configuration would look see something like this:
UUID=b87de212-52ca-4600-9e30-6e80e24df1ed / ext4 errors=remount-ro 0 1
  • You need to add barrier=0:
UUID=b87de212-52ca-4600-9e30-6e80e24df1ed / ext4 errors=remount-ro,barrier=0 0 1
  • Finally you have to reboot your server.

Another thing that you could do is use the MySQLtunner script to test your SQL instance and adjust your settings:
