mpz_probab_prime_p(n, reps) : how long?

[jojo 29]

Hi,

First, excuse my poor english (It's not my native language, I'm french).
Then, do you have an idea of how long an Athlon XP 2200+ (1.8 GHz) needs to 
execute the function mpz_probab_prime_p(n, reps) with n, a 33 million digits 
prime number and reps = 10?
