About cores,tests... - HTC Amaze 4G

Hello everybody,
My friend and me(we have s-on and ics stock last version) when we tried quandrant we usually get 2700 scores.But he told me yesterday he tried different way that he added one line in "buid.prop" and he got 3600 marks quandrant scores
When he opened quandtrant benchmark system information he saw just 1 core is writing.He thought we should see 2 cores because we have 2 cores and ics (even leak)version.
So he wants to added in build.prop ''persist.sys.ui.hw=1'' and he wiped dalvic cache and cache and fix permission then restart system.He checked quandtrant standarts and he saw that 2 cores were writing there and immediately he got run full benchmark and got 3600-3500 marks.So we think that the reason of 2 cores.
But when he checked after 20 min later it was writing again 1 core in quantrand system information.It s chancing by itself.we can get more performans? is it possible to keep it?
I remember some guys talking about cores and they told just check antutu you gonna see 2 cores.Second core works when need it.But my friend added ''persist.sys.ui.hw=1" this line in build.prop and maybe he made 2 cores active So what do you think about it?Maybe somebody try this way and share results with us?

The first few pages of this threadhttp://forum.xda-developers.com/showthread.php?t=1616669 talked extensively about dual-core and quadrant scores, and I would say by page 10 it was agreed upon that quadrant really just sucks. Go check it out, maybe that will shine some light for you..
I remember reading about how ICS improved dual core support, and I could have sworn it was on developer.android.com but I can't find the article that explains it now(and too many results to sift thru) - but basically the tweak "persist.sys.ui.hw=1" would have been found in gingerbread roms, because it DID increase performance, however with the way ICS handles the threading of dual-core+ processors that shouldn't do anything.
And before someone comes in here and says this in a not-as-nice way, be careful using quadrant benchmark as a tool- if ONE little detail is different, you will get TOTALLY different results! A different launcher, a different setting, or even having different background processes or having recently run a different app will change the score TOTALLY. Run it 10 times, chances are it will put out wildly different numbers - now go run 10 apps, then go back into quadrant and run it 10 more time - again, wildly different numbers, no consistency.
Besides, all that REALLY matters is your experience - if your score goes up a thousand(consistently somehow) but it doesn't work noticeably smoother, faster, or better- then what does your score matter? You could add 2 more cores, another gig of ram, better gpu - but if you can't NOTICE a difference then what would the point be?
It is easy to find why people added 'persist.sys.ui.hw=1' to gingerbread, but I can't find ANY documentation/posts that give a real reason to add it in an ICS build.. hope this answers your question.
And if anyone can find the link to googles explanation on how ice cream sandwich handles multi-core cpus compared to gingerbread can you PM it to me?

Thanks my friend your answer.Just ı got that if use quandrant benchmark test when ı check system information if ı see 2 core ı get 3500 marks but if ı see just 1 core system informatin ı can get 2700 marks.
So it depents on cores ı see.Its fault of benchmark app or our phone works one core just when need it use second core?
