Do you mean by 5 seconds on the start: The time that Sage needs to start up would increase by 5 seconds? I think many people would think that the startup time of Sage is already too much, so, increasing it further wouldn't be good. -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org

Re: [sage-support] Re: Sage problem
Dear Simon, I have base about 1 MB prime factors which occured in many factorizations x^n-1 , Lucas, Fibonacci etc. I don't adding any successive primes only primes which occured in siome factorizations (my base also contained Cunningham base and 100 others) Algorhithm of probe factorziation is very simply. Take successive primes from base smaller as factorized number and by GCD method checked that this prime divisor occured in factorized number. GCD algorhitm is very quick that scan whole baseneed few seconds but finding big factors even with NFS method (not implemented in SAGE yet) need lot of time. That is worth lost 5 second on the start and lot of very big numbers can be factorized completely on this method during 5 seconds only.

At least according to the benchmarks at http://sagemath.org/tour-benchmarks.html (factorization of 2^512-1), Sage is not bad at factoring integers. So, I guess using the existing implementation of factorization algorithms is a good starting point. Of course, if you observe that in some applications factorization is too slow and you know how to improve it, then you are welcome to demonstrate how.
