performance - Most efficient code for the first 10000 prime numbers?

I want to print the first 10000 prime numbers. Can anyone give me the most efficient code for this? Clarifications:

  1. It does not matter if your code is inefficient for n >10000.
  2. The size of the code does not matter.
  3. You cannot just hard code the values in any manner.

The Sieve of Atkin is probably what you're looking for, its upper bound running time is O(N/log log N).

If you only run the numbers 1 more and 1 less than the multiples of 6, it could be even faster, as all prime numbers above 3 are 1 away from some multiple of six. Resource for my statement
