Ok, I see, the effect may be only on my dev machine.

gentoo linux, PHP 5.2.14 (default php config):

int
original TRUE : 0.034
variant1 TRUE : 0.029 gain 19.7 %
variant2 TRUE : 0.020 gain 69.9 %

negative int
original TRUE : 0.034
variant1 TRUE : 0.028 gain 21.4 %
variant2 TRUE : 0.020 gain 73.7 %

largest int
original TRUE : 0.038
variant1 TRUE : 0.031 gain 20.8 %
variant2 TRUE : 0.020 gain 94.9 %

int as string
original TRUE : 0.031
variant1 TRUE : 0.036 gain -15.4 %
variant2 TRUE : 0.026 gain 18.9 %

negative int as string
original TRUE : 0.031
variant1 TRUE : 0.035 gain -10.9 %
variant2 TRUE : 0.026 gain 17.3 %

zero
original TRUE : 0.030
variant1 TRUE : 0.026 gain 18.4 %
variant2 TRUE : 0.020 gain 53.9 %

zero as string
original TRUE : 0.028
variant1 TRUE : 0.030 gain -7.4 %
variant2 TRUE : 0.025 gain 11.6 %

negative int as string with leading zero
original FALSE : 0.031
variant1 TRUE : 0.033 gain -5.5 %
variant2 TRUE : 0.026 gain 18.4 %

But on a (productive) debian, PHP 5.2.6 (with eaccelerator v0.9.5.3)

int
original TRUE : 0.039
variant1 TRUE : 0.030 gain 30.0 %
variant2 TRUE : 0.025 gain 56.9 %

negative int
original TRUE : 0.039
variant1 TRUE : 0.031 gain 26.1 %
variant2 TRUE : 0.025 gain 53.5 %

largest int
original TRUE : 0.046
variant1 TRUE : 0.037 gain 26.2 %
variant2 TRUE : 0.025 gain 87.2 %

int as string
original TRUE : 0.037
variant1 TRUE : 0.036 gain 4.0 %
variant2 TRUE : 0.031 gain 19.7 %

negative int as string
original TRUE : 0.037
variant1 TRUE : 0.035 gain 6.5 %
variant2 TRUE : 0.031 gain 19.8 %

zero
original TRUE : 0.037
variant1 TRUE : 0.030 gain 26.9 %
variant2 TRUE : 0.024 gain 52.9 %

zero as string
original TRUE : 0.036
variant1 TRUE : 0.033 gain 9.7 %
variant2 TRUE : 0.030 gain 20.3 %

negative int as string with leading zero
original FALSE : 0.037
variant1 TRUE : 0.034 gain 7.0 %
variant2 TRUE : 0.031 gain 18.2 %
