st: Use of stata and maximisation of one's computer capabilities

Hi,
I am running a set of models in a multinomial logit model framework, using 4,000,000 observations, 3 choices (plus the reference category) and 54 variables. Stata takes 40-60 mins, running each the model.
I ran my code in two different machines:
1) A Win 2008 R2 terminal server (2x quad core/16HT cores, Xeon E5540 @2.53GHz, 32GB RAM, 500+GB free disk space) -using Stata/SE 10.0
2) A Mac 2.66 GHz Intel Core i7, 8 GB 1067 MHz -using Stata/SE 10.1
Despite of these machines’ capabilities, my models take too long. I have set the memory usage to:
On the Win server:
current memory usage
settable value description (1M = 1024k)
--------------------------------------------------------------------
set maxvar 32767 max. variables allowed 12.501M
set memory 1024M max. data space 1,024.000M
set matsize 4500 max. RHS vars in models 154.873M
-----------
1,800.169M
On mac:
current memory usage
settable value description (1M = 1024k)
--------------------------------------------------------------------
set maxvar 30000 max. variables allowed 12.390M
set memory 1024M max. data space 1,024.000M
set matsize 10000 max. RHS vars in models 763.779M
-----------
1,800.169M
Is there any way to take advantage of the full capabilities of these machines? Do anyone have any suggestions on an “more" efficient way (in time terms) running my models using Stata?
Regards,
Francisco.
