Joe Lauzon was widely reported to be tied with Demain Maia, Terry Etim, and Nate Diaz for most Submission of the Night performance bonus wins, at four each.

Joe Lauzon vs. Chris Warburton, UFC on Versus 4/UFC Live: Kongo vs. Barry, June 26, 2011
Joe Lauzon vs. Gabriel Ruediger, UFC 118, August 28, 2010
Joe Lauzon vs. Jeremy Stephens, UFC Fight Night 17/UFC Fight Night: Lauzon vs. Stephens, February 7, 2009
In addition, Lauzon has won three Fight of the Night bonuses:
Joe Lauzon vs. George Sotiropoulos, UFC 123, November 20, 2010
Joe Lauzon vs. Sam Stout, UFC 10, January 2, 2010
Joe Lauzon vs. Kenny Florian, UFC Fight Night: Florian vs. Lauzon, April 2, 2008
However, Lauzon reportedly won a Submission of the Night bonus for choking out Brandon Melendez at the TUF 5 Finale, and a Knockout of the Night bonus for his 48-second KO of Jens Pulver at UFC 63. but these bonuses were never officially announced by the UFC.
Kevin Iole refers to the KOOTY here.
The UFC's own website refers to him as having won Submission of the Night five times (Warburton, Melendez, Stephens, Ruediger, and Melendez). They also credit him as well with a KO bonus for the victory over Pulver.
"Has won Submission of the Night five times (Guillard, Warburton, Melendez, Stephens, Ruediger), Fight of the Night three times (Sotiropoulos, Florian, Stout), KO of the Night once (Pulver)"
Thus, with two more tonight, it appears that Joe Lauzon is the Performance Bonus 'of the Night' leader in the UFC. Not to be overlooked, Lauzon's 11 bonuses come from 13 UFC fights, while Anderson Silva's 9 have come in 15 fights and Lytle's 10 bonuses coming in 20 UFC appearances, making Lauzons feat that much more impressive.
