Just guessing broadly, but
1. Get a faster computer.
2. Rewrite the internals of -psmatch2- in Mata.
are my (non-facetious but possibly not practical) suggestions.

I am using -psmatch2 on stata 11 version. My sample is close to 250000
observations. I ran the following code
psmatch2 improved, pscore(pscore) outcome(diarr) common caliper(.001)
neighbor(5) trim(5)
The issue is it takes forever to show results. The code is running for
last 24 hours with no output. It is computationally intensive. I
wonder if there is an efficient way to do this in less time.
Sometime, two days pass by without any output. KIndly suggest if you
know how to do it efficiently.
