What makes a query slow?

Slow queries can mean your database does more work than it needs to, which means it’s using more resources than it needs to. When limited resources like CPU or I/O run out, everything can start to slow down. Inefficient use of resources is also a problem when you’re not using the resources you have.

Is SQL faster than Python?

If the procedure mainly deals with SQL, fetching and filtering data, it will tend to be faster than host language code like Python. The more data that needs to be processed the more this will be true simply because of the cost of moving the data from the database’s memory to the host language application’s.

Why is SQL query taking so long?

There are a number of things that may cause a query to take longer time to execute: Inefficient query – Use non-indexed columns while lookup or joining, thus MySQL takes longer time to match the condition. Table lock – The table is locked, by global lock or explicit table lock when the query is trying to access it.
