Memory Size (4.1.2 vs 4.2.1)

Ok, thanks to everyone's help here, I just finished doing a minimalistic compile of PHP 4.2.1, (removing mysql, posix, session, and xml). However, I then replace my existing 4.1.2 with it (yeah, I was upgrading at the same time - If I had to recompile, might as well) And I was suprised, even after removing those parts, the memory req didn't seem to change much: Before: (stock compile of 4.1.2 plus GD) Apache process took 5.5Mb RAM, 1.8Mb resident After: (reduced compile of 4.2.1 plus GD) Apache process took 5.2Mb RAM, 2.0Mb resident So the overall size dropped, but the resident rose. And overall, not by that much? So is 4.2.1 that much bigger to cancel out the reduced compile? Or are removing those parts just so small that it doesn't make much of a difference? Eli
