st: Propensity Score Matching

I am new to Stata and propensity score matching. I have 143, 110 control and
5,862 treated in my matched samples. I ran pscore2 to get this.
Once I ran pscore I ran a radius matching method with the following command:
. attr englleve sch_grp sex_1 rd07leve, comsup boot reps(100) dots logit
radius(0.0001)
The process has given me:
ATT estimation with the Radius Matching method
Analytical standard errors
---------------------------------------------------------
n. treat. n. contr. ATT Std. Err. t
---------------------------------------------------------
5862 143110 -0.073 0.008 -8.673
---------------------------------------------------------
Note: the numbers of treated and controls refer to actual
matches within radius
The process has now run for 36 hours (MP2 version of Stata 12.1 AMD 2 core,
WinXP pro 32byte). Should I let it run longer or am I hopelessly lost in
some computational problem? Or did I miss specify the model?
Thanks for your help and advice
Ted
