...lower than Ruby and Perl, and, comparing Python versions, 2.7.6 is quite a bit faster than 3.4.1
Use the POSIX-compliant awk + sort + cut combo as a last resort; which awk implementation you use matters (mawk is faster than GNU awk, BSD awk is slowest).

Time complexity of Sieve of Eratosthenes algorithm
...ch is O(n log log n). (See here or here.)
The "find the next prime number" bit is only O(n) overall, amortized — you will move ahead to find the next number only n times in total, not per step. So this whole part of the algorithm takes only O(n).
So using these two you get an upper bound of O(n...

If your types are a bit more complicated (e.g., often you're dealing with JSON-compatible values, which are hashable, or lists or dicts whose values are recursively the same type), you can still use this solution. But some types just can't be co...
