"Disable Reverse DNS"

[AlanDewey]

New to SMF.
Following the suggestions for speeding up the site.
One is to 'disable reverse dns'.   
However, I can not do this through administration because it tells me   settings  is set to read-only.  Every which-way I check, that file is not 'read only.'

Rather than fight that, if someone could give me the exact syntax I will just manually enter it in the file.

(I hope this was not already asked and answered; I searched the manual and the forum and did not find any mention of this.)

Thank You.

You can't configure this in a file as it is a thing configured in the database.

You can configure this in the database by going to phpMyAdmin, finding the settings table and adding a new row where the "variable" column will have "disableHostnameLookup" in it and a value of 1.
