I concur my first assignments in 1997 took about 25 days on a Celeron300 @ 504mhz. The fastest P3 of the era was 500Mhz.
I found Anandtech, began overclocking, and found GIMPS shortly afterward.

It seems I remember them taking much longer. I think I ran Prime95 in the very early days, was absent for a while, and then restarted in 2002 or so. At that time, a single LL on my machine took substantially more than a month (I think); now I'm turning in two a month. My impression would be that machine speedup is outpacing the slowdown due to exponent size.
Strictly from memory, though...And it may be my memory that's old and slow. Norm

A belated congratulations to all involved!
By the way, is it possible that there are similarly unaccounted for primes in the 17 or bust project, collecting dust somewhere? It has just been way too long since they found their last prime.

There are only 100150 CPU fulltime modern cores equivalent currently working at SoB, so progress is slow. There is some overlap with the Prime Sierpinski Project, so that doesn't include all the effort towards finding the remaining 6 primes to be found. Also, there is other work being done via Boinc.

The teraflops/second metric just spiked. What happened?

Was it the NT Service flavor of Prime95? Services cannot make sounds.
