Results comparing S41.07 with

Results comparing S41.07 with S41.06:

Athlon64 3400 - S41.07 is 5% faster
Athlon64 2800 - S41.07 is 6% faster
Sempron 2600 90nm - S41.07 is 6% faster

Sempron 2500 (older) - S41.07 is 0% faster
Athlon 2500 (Barton) - S41.07 is 0% faster

Interesting, the newer cores are all 5-6% faster with S41.07
The older cores are the same with both clients

One much older machine running a Tbird core:
D41.14 is running 6.5% faster than D41.13

All work units validating with no errors so far on the above versions.

Thanks Akos for all the hard work & great clients!

Still NO Invalid results for

Still NO Invalid results for S41.06 after about 100 results :)

Since you started all this Akos, I have only had one invalid result back on 13apr06 using D40. Does not seem that long ago we where trying to beat the 4x mark. Now we are at the 6x mark. WoW.

Standard app @ 280 min / S41.06 @ 44 min = 6.3636 x faster

98SE XP2500+ @ 2.1 GHz Boinc v5.8.8

S41.06 is the best yet for

S41.06 is the best yet for older single-core CPUs, and I haven't seen any errors. Look at what it did for this old 700 MHz P-III -- shaved about an hour off the already outstanding performance of S40.12 on long WUs!!! A 3.6 GHz Xeon with the standard client took 2.6 times as long as my 700 to crunch this WU! But hyperthreaded chips still do best on S40.04 or S-39L.

Yes, but why should the HT be used? At least for Prescott 3.4 GHz - if you turn the HT off, you will be significantly faster with S40.07 than with HT_enabled_S39L.

Could somebody try out this version of S41.07 on a HT enabled system?

partial should be done baking in about 5 seconds.

other unit of the HT seems to be cooking along nicely.
