Stata is fast
On an 2.8 GHz Pentium 4 running Windows XP,
- 0.022 seconds: Stata sorts 10,000 observations.
- 0.130 seconds: Stata reports summary statistics on 25
variables.
- 0.050 seconds: Stata runs a linear regression (10 covariates).
- 0.088 seconds: Stata runs a logistic regression (10
covariates).
- 0.605 seconds: Stata runs a stcox regression (10 covariates).

Stata/MP, a
parallel-processing-capable version of Stata/SE, is even faster.
