st: stata runs slowly

Hi,
I have a problem with Stata running very slowly.
My population contains about 1 mio observations. I am doing an
cox-regression analysis, stratyfied on families:
stcox i.education, strata(family-id) vce(cluster person-id)
This command runs without any problems.
However, when I want to perform the following un-stratyfied analysis -
where I am still taking into account that some of the persons are
related - , it takes stata several hours to do so:
stcox i.education, vce(cluster family-id)
Can I do something to make this run faster?
Thank you
