Does Storing Large Data with update_option Affect the Speed?

Hi all,

I’m making a plugin which uses the update_option(), and wondering if storing lots of data in the option slows down loading pages.

Actually the data is a log data to record the plugin’s activities. If I make a text.log, I have to make the directly’s chmod 777. If it is only me using it, it’s ok but if I’m going to let everyone use it, I’d like to make it extremely easy to use.

So, I thought it might be a good idea to store the logs in the option and I’d like to know when the options’ being loaded, in order to make sure if they don’t affect the speed of loading pages.

I appreciate your information.
