This is less than 10% but it does show that there's a difference. (I ran the benchmarks more than once and got pretty stable results; I used 7,777,777 iterations; I got no change in results from dry2 than dry2reg.) -- Paul Vixie La Honda, CA "Illegitimi non carborundum." <paul@vix.com> pacbell!vixie!paul (dont let the bastards grind you down)
