Added in 3.1
Sets the "refresh rate" of the Text Area.
When N is set to a number larger than 0, AdiIRC will try to detect burst of messages added and then try to redraw the textarea less often which increases the speed of adding lines.
Larger <N> value makes it faster, since every system is different try experimenting with different values in the range of 10-100.
See also $fupdate.
|<N>||If N = 0, disables the refresh rate system, otherwise AdiIRC tries to redraw every N milliseconds as long as the bursts is happening.|
