hey, last night i made a program that will tell you whether or not a program is prime (with a lot of help from some other people, most notably RoD and Alpha) and i used it to create a basic program that lists out the amount of primes you specify, and, if its more that 300 (the amount of lines in the DOS window) it prints them to primes.txt. i was wondering how long it takes you guys for the program to print out a lot of them. for my 2.0 gig processer with i think 512 ram its instant up to about 10000 (ten thousand), and took close to 5 minutes for the first 200000(two hundred thousand). if you could download it and try it and give me some times, it would be appreciated. the program will tell you when the primes are written out.
