If you do a "show ip protocols" with IGRP running, you should see something
like the following, (only the first three lines).

Routing Protocol is "igrp 10"
  Sending updates every 90 seconds, next due in 7 seconds
  Invalid after 270 seconds, hold down 280, flushed after 630

It's not hard to turn those intervals way down and send your broadcasts
every 5 seconds instead of every 90 seconds, however you probably want to
turn all of the timers down so that invalid is still 3 times longer than
updates, the other timers are not as important, but it's best to make them
all proportional to the decrease.

The following is what I would call "IGRP on methamphedamines" (speed).

* * *
router igrp 10
 timers basic 5 15 17 35
* * *

Would give you a show ip protocols that looks like this...

Routing Protocol is "igrp 10"
  Sending updates every 5 seconds, next due in 4 seconds
  Invalid after 15 seconds, hold down 17, flushed after 35
