Sounds like you may also have a problem with your database structure. A query that fetches 800 records from a table with only those 800 records in it should not take a full second - it should be milliseconds.

Make use of the `EXPLAIN` function to find out what your queries are trying to do and what indexes they're trying to use.

```sql
SELECT property_id, property_capacity, property_rooms
FROM properties
WHERE property_status = 2
```

This query should ideally be using an index for `property_status` to filter your records. Do you have an index on the `property_status` column? Go through each of the queries you're finding slow and identify whether you have appropriate indexes for it to use.
