I recon a 10% difference is good going for any credit system



My first two results for the same coputer
3,324.83 secs 7.57 credit = 439 secs for 1 credit
3,557.41 secs 9.00 credit = 395 secs for 1 credit

So we have ~11% difference between these two tasks on the same computer.
Really they should be the same time for 1 credit but that\'s never going to happen :-)


Is that good enough? Not a large sample though, that could only make it worse ;-)

Well its an improvement over the difference generated by using an optimised client :)

The difference for the same computer/client is very good, say using the comparison above but looking at BOINC credit (I think this is currently using 5.5.0)

But of course what you mean is between 5.5.0 and 5.4.9/11 well that would be around a 300% difference ;-)

Now two computer returned results (all results are since this morning)


Like I said it can only get worse.


AthlonXP 2500+ stock
11 results

MAX seconds/credit = 439
MIN seconds/credit = 261

difference 168% from min to max
(ave = 357 seconds/credit)



Pentium III-m 1GHz

MAX seconds/credit = 744
MIN seconds/credit = 529

difference 141% from min to max
(ave = 630 seconds/credit)


Certainly needs to be improved from just my few results returned
