Could you give more details ? If I understand Gerhard correct, some functions take primelimit not as an advice about the number of available primes, but as a directive to loop over these primes. Suppose I want to have a table of primes up to 1e9 (very easy with the current PARI), say, to use forprime() with big primes. This may significantly slow down the functions which loop over *all* existing primes. Ilya
