- I have a database with quite a few VARCHAR fields. When the database was first built the lengths of the columns were set a bit larger than absolutely necessary.
- Now after, having used the DB for a while and run a lot of data through it, I have a better idea of how long the fields need to be and am wondering about if reducing the VARCHAR lengths would make it run better.
- If I set the lengths to say 10 characters plus what is currently the max length would that help the select and join times?

Would a MySQL database run more efficiently with smaller varchar lengths?
