What are your periteration times?
I am just curious about what some of your periteration times might be.
M 46,878,773 = 0.024 for me.

I'm doing 2 double checks of ll I think and my minimum I can see so far is .078 I'm not sure if they are double checks or not.

3040msec on M24,262,141....Liquid Nitrogen has a relatively "hot" machine.....

My machines are a bit old, but out of curiosity for what others are able to output, I'll post what I can. I hope this is not simply a low brow "mine is bigger than yours" thread. In today's age of computers, your unit will be blown away eventually by what I replace it with when the time comes.
I had four machines (now three, since two weeks ago  one TF and now P1 for GIMPS, the rest SoB). Three are Intel Core 2 class. Depending on the system's resource allocation and relative "cleanliness", I get: Core2 6300 @ 1.86: LL ~0.059 19913348, 19913348 (moved now to GIMPS P1 & LL  47907107  timings, soon to come) Core2 4300 @ 1.80: LL ~0.080 19880194. Not currently running (too hot, even with a laptop fan cooler  used as a heater during winter  thanks HP!): AMD Mobile K10 X2 RM72: LL ~.110 19913348.

M28865407 (1536K FFT) > 0.010  0.011 msec/iter (using two cores of a slightly OCed i5750  timing fluctuations are due to variations in the type of work done by the other two cores: e.g., if I use both of them to P1 testing, I get 0.011 msec/iter; if I switch one of them to TF I normally get 0.010.

:) It's an overclocked i7870 @ 3.9 GHz. This is my "spare system," it has single core speed that is slightly faster than a stock Gulftown (i7980X @ 3.33 GHZ)

It will be faster than whatever you can buy until the year 2018 or maybe longer. :)

Use "PercentPrecision=6" in prime.txt then you get maximum precision and decimals on the milliseconds.

Yeah sorry I forgot that there are 2 settings for precision, one for progress and one for timings. I have had those on since I started GIMPS. I should have checked undoc.txt before posting:
Code:
You can adjust how many decimal digits of precision are displayed in lines output to the screen. In prime.txt enter a value between 0 and 6: PercentPrecision=n You can alter the way the program outputs timings. In prime.txt set: TimingOutput=n Where n=1 for seconds with 3 digits of precision, n=2 for milliseconds with 1 digit of precision, n=3 for milliseconds with 2 digits of precision, n=4 for milliseconds with 3 digit of precision.
