I don't worry about it :) I think, this some seconds doesn't matter, it's only about 1.5%, it's not relevant imho (mesaure error :)).

Actually, it is a 5.71% increase (computed as: 14 seconds / 245 seconds).

Thank you for results. Since we are on page 2 now, i modified my first message and added your results. Let us now more results.

1min 38s - Intel Core i7 2600K (3.40 GHz - precompiled FET with Windows 7

Thank you for the result. i updated my first massage again.
Maybe someone has a new netbook with an intel atom or amd fusion cpu? whould be intresting to know their time.

Important note: it seems that GNU/Linux FET might be faster than precompiled Windows FET.

On my computer, I have 64 bit GNU/Linux openSuse (64 bit compiler gcc) and 64 bit Windows 7 (32 bit compiler MinGW).

The Windows FET seems about 15% slower.

Maybe if using MSVC compiler under Windows might get better results for Windows FET.

5min 50s - Intel Pentium E2140 (1M Cache, 1.60 GHz, 800 MHz FSB)
Precompiled FET
Windows 7 32-bit

Thank you for report. I also done a new benchmark:
2min 01s - AMD Athlon II X2 270 (3.40 GHz - compiled and generated with Linux)

i added both results into the first message.

please sent us more results.

y

Two more benchmarks:

4min 21sec - Intel Celeron E1500 (2.20 GHz - precompiled FET with Windows Vista 32bit)
6min 57sec - Intel Pentium 4 530 (3.00 GHz - precompiled FET with Windows XP 32bit)

y

And a final one (at least for today):
4min 26sec Intel Mobile Core 2 Duo T7300 (2.0 GHz, 4MB L2 cache - precompiled FET with Windows Vista 32bit)

For GNU/Linux, you need to care about the Qt version. Qt 4.8.0 is slower than Qt 4.7.4 on my computer.

repeat 5 :
41s - 1m1s - 46s - 1m42s  - 51s

min: 60.2 sec

intel i7 - 2670Qm 2.2GHz

Hallo silver,
i am not 100% sure what you have done. maybe you didn't always use the "correct" seed?
Can you please explain a bit more detailed your results and/or repeat them with the correct seed, file and fet version?

Silver

#28
if you mean seed x=1 y=1 :
intel i7 - 2670Qm 2.2GHz
with windows 7 = 2m 5sec
with ubuntu 11.10 = 1m 50sec

regards

Volker Dirr

thank you.
i added all previous results in the fist message. (so also results from y).

since the first message grow and grow i just want to know this:
- is it needed to split it into 2 tables? one for windows and one for linux? (because the linux variants are always ~10% faster)
- is it needed to cut results that are slower then maybe 5 minutes?
