Forums mIRC Help Are global variables stored in memory?

The topic basically says it: are variables which are set with the /set command loaded into and read from RAM memory (like /var) or - since they are stored in vars.ini - constantly read from the HDD?

In other words, how 'bad' is it to use a global variable in a script that is constantly triggered?

The help file wasn't too clear about this. The application of /var -g isn't too clear either, regarding the fact that those variables only exist for the duration of the script routine.
