Keep in mind that default RH and Debian kernels treat threads differently.
Debain uses the old threading model which gives each thread it's own entry
in the process table. RH uses NPTL, wich does not give each thread it's
own entry and, thus, requires less overhead, so what you are seeing is
probably a reflection of the Kernels' threading models _not_ a diffetence
in ps. If you want the new behaviour on Debian, I recomend upgrading your
kernel to a 2.6 series which will also improve your performance.
