What causes mysql query speed to go down?
Busy MySQL databases go through thousands of data insertions and deletions per week. All this data deletion leaves “holes” in the database, which is called fragmentation. When fragmentation in a MySQL table goes above 15%, it might affect the query speed. But this usually becomes a problem only for databases that are more than 1 GB in size.
