I want to make sure AJAX responses from dynamic JSON pages does not slow down the server when the SQL queries take too long. I’m using PHP, MySQL with Apache2. I had this idea to use ini_set() to recude the execution of this pages with the inline use of the mentioned method or the set_time_limit() method. Is this effective? Are their any alternatives or a mysql syntax equivalent for query time?
these are being used for example with jquery ui autosuggestions and things like that which is better to not work if they are gonna slow down the server.
If it makes sense for your application, then go ahead and set_time_limit with the desired max execution time. However, it most likely makes more sense to tweak your queries and introduce caching of query results.
