Lightbulb You will get lag 9 times out of 10

Yes of course, you've just flushed your cache! This script will harm performance in most cases except in extreme situations where you will only use one app loaded freshly into memory.

Memory "optimisation" was all the rage on Windows back in the day, and it was a hoax (fully debunked by Mark Russinovitch in his excellent article "The memory optimization hoax"[1]), because 9 times out of 10 the kernel was a better estimator of reused binary data and memory page handling than the clueless user. Now we have the same "optimiser" for android, and I'm pretty sure 9/10 the same logic applies.

Recently these "optimisers" have started hitting the Mac app store, and they have been thoroughly discredited except in very rare use cases, yet naive users write they see more FREE memory (no they don't, they just see the result of readjustment of memory pages that the OS calls free but are no more FREE than they were before...).

Even the article he links to, many comments say this tuneable is for benchmarking, and doesn't help in optimisation in 99% of the cases.

No one has yet proved that flushing clean memory cache magically works better on android than it does on linux/os x/windows. I asked imbawind back in the old thread and his answer showed he "thinks" it works, but has no evidence it does.

Anyway, apart from getting lagginess as the android kernel repopulates useful cache data, nothing gets harmed so if you like the ⚡boosting⚡ placebo™®©℗ then enjoy...

thanks for the loooooooooonnnnnnnnnnnng comment you have typed but all sources you have saw, make you feeeel like a pro are for pc/laptop, arent they?

yes, you may say 'Android is based on Linux, so if linux blah blah blah , Android are similar blah blah blah'

you asked me, now i ask you: how many ram do we have and how many ram do a pc/laptop have?

are u gonna to tell me that your phone are smoooooth when you have only 60/50/40/30/20/10/5/1 (mb) available left?

but how about pc/laptop? are u gonna to tell me they lag when they used 278mb of ram too ?

cache is meant for smoothness in higher spec machines because they may have 2/4gb of ram
like what i have said in first post:
Quote:

Boost it only when it's needed

only boost when u feel lag then there wont be a problem !

always remember smartphone isn't exactly same with pc, especially low end smartphone

Quote:

this tuneable is for benchmarking

this is bull**** for SGA, benchmark get even lower score after boost ,why ? benchmark a test for overall system performance, including CPU. we have cleared the ram so the cpu will work hard to create them back, in the other hand, cpu still need to handle the benchmark, thus you won't get higher score in benchmark cuz we only have 800mhz, single core

where
btw, i'm not gonna to bluff you, you can see users' feedback (but sadly many threads have been deleted by moderator, this is a new thread thus u cant see many comment here )
anyway, i accept criticism, but at least, you should try urself before leaving a negative comment here

many users(Ace,Fit,Gio,X10,X10 Mini,X10Mini Pro,X8 and many more) who have tried the Arenaline Boost told me that it really work, like more smooth when scrolling
here are some users' feedback

i dont need to say too much, users' review represent everything


last, thank for your time to type the long comment, it increase my knowledge cause it make me to google

sorry for my english as it's not my primary language

it's normal
sometimes u will feel lag when using some apps because it's caches are still in use
after boost, u cleared all in use and not in use cache, cpu need to create it back therefore u will notice some feel lag but it will be much better after a few minutes, then u will notice the overall performance increase

Can you flash the new V2 the same way we did to V1 or do we need to delete V1 first.

Hi imbawind, my comment certainly wasn't personal, thank you for taking the trouble to contribute to these forums. :beer:

I am not a kernel engineer specialised in low-memory systems, and I think neither are you. I do know that a lot of work goes into building the virtual memory system and read/write caches in OSes and people much more knowledgeable and talented than us tune, patch and rewrite the kernel to maximise its use. Google doesn't employ monkeys to slap any old kernel into an OS it has invested a lot of resources into, engineers work on this stuff day and night.

Obviously a smartphone has less memory, but that doesn't mean the relative scale of resource demand to supply is not similar to desktop (smartphone apps don't request huge chunks of memory like desktop apps, so perhaps the % demand isn't so different). But my major conceptual issue is in flushing data from caches applies to smartphones and desktops equally. If the kernel uses that data again (and it has lots of optimisations to manage disk / memory caches), you get a performance hit if you flush.

Regarding what users say -- sorry that certainly doesn't mean it actually "works". A couple of years back I was engaged in a dialog with the developer of a memory optimiser for OS X and he told me lots of users said it worked great, yet when he tried to show me measured evidence, he never could show anything other than negative performance. Lots of people are led by what they are told, it is human psychology and works for advertising since the beginning of time; SuperDuper Product X™ will make your computer better -- then it tells you you have "freed" memory and they don't understand it never freed memory, it just renamed inactive memory pages to free ones so the OS reports more free memory. That is why on the desktop it is called a hoax. It would take a clever computer scientist many iterations of benchmarks to tell us whether /proc/sys/vm/drop_caches really helps or harms smartphone performance and neither you or I or anyone else have that data.

But anyway, as I said above, apart from losing cached data the kernel may have to reread back and slow you down a bit, if people enjoy typing the command and feeling they've done something with this script, then that is great. Remember that placebo medicine is very good medicine, it has a measurable positive effect, and is cheap and invariably harmless ;)

i think u still not even tried this
i have nothing to reply you , placebo or working , decide by users

Yes, I have because this was built-in to Engengis which I used since I first got my Ace, and actually made this command alias in my bashrc file some time ago when I first started playing with terminal:

Code:
alias flush='sync;sleep 1;echo "3" > /proc/sys/vm/drop_caches;echo "1" >  proc/sys/vm/drop_caches;sleep 1;echo "==> Cache Flushed <==";'

do you really clear those cache when your phone laggs alot even you have cleared all app ?
Adrenaline Boost is meant for those situation like you have used 150mb ram even though u hav cleared app using task manager, then if u boost at this time , u will notice a big different
but if u boost when u have only 110mb use ram after cleared app, then u will feel that this is SuperDuper Product
