what exactly is a query
 

what is it and how does it effect the board???

uhh ill try my best :\

a querry is when php looks for some specific info in the database

i think

and depending on what the querry does is how it would affect the board, if there are too many large querrys it will make the computer work harder

so the less query's there are the faster the board will load???

A query is a request sent to the database that optionally returns data in the form of a matrix (2D array or rows of columns).

The more queries, the more communication there is between the MySQL server and the client (not necessarily PHP), the higher the server load becomes, and the slower the page loads.

how do u reduce queries?

Don't hack vB, or don't query the database unless you absolutely have to.

Also, you can reduce queries by some of the board optimization hacks

^^^ which hacks would be good for that

filburts or Xenon's, both are equally good

could i get a link :)
