ProfileMatic & Drop Cache = Infinite memory!!
 

Hi guys!

I has an IDEA!

ProfileMatic comes with the "Custom action" -thingy which is nearly no use for me with my skills, but could we implement a script there which runs Drop Cache's "Free all"?
I don't know much of any scripting nor coding, but this could be a fantastic improvement. Free memory when ever you want, automatically.

Anyone?



Step-by-step guide:

1. Install Drop Cache & ProfileMatic
2. Fire up the ProfileMatic
3. Create a profile like:

Time:

Starts: 06:00
Ends: 06:01
Every day!!

Custom Action:

Custom action on rule activate:

Code:

---

aegis-exec /opt/dropcache-mdn/bin/dropcache.sh --3

---

4. Save
5. Enable rules in ProfileMatics settings.
6. Tsadamn! You've made a script which will clear your cache and free memory at 06:00 every day.

Good luck! It shouldn't be hard.

I have been using this for 4 months without any noticeable battery drain, sluggishness, phone warming up.. Nothing at all. This trick seems cool to me. Just make it do the "refresh" by night time or when you usually charge your phone, just to make sure you don't get any surprising battery drain during your work-day.

Wow man that could be awesome, been wondering how this could work.

Re: ProfileMatic & Drop Cache = Infinite memory!!
 

This should work... First of course install DropCache. Then add one of the following to ProfileMatic's Custom action.

Free pagecache:
Free dentries and inodes:

and what effect might this bring?

if the kernel needs memory it will free whatever memory can be freed (normally the cache). If not, what's the point of freeing the caches? your N9 will have to reload stuff again -> slower + more battery consumption.

please leave the kernel alone!

Re: ProfileMatic & Drop Cache = Infinite memory!!
 

The benefit I'm looking here would be that the N9 really feels sluggish from time to time. Let's say that 1 minute would suck alot, BUT how about a free memory every 3-24h example.

Same point that the Drop Cache would do, but an automated system that you don't need to bother click click clickety clicking it from time to time to make your N9 run smoother. I'd say it wouldn't be a noticeable battery drain, If used with caution.

Of course, I'm not an expert and this is just my opinion on this. Feel free to explain and give your own opinions. We really need them!!

I'm still wondering does this cause some complications to apps like Wazapp which runs on background and is "idle" nearly 100% of the time? Will they crash / stop while freeing cache? Or does the Drop Cache just affect the cache that is NOT in use by any running application?

I tested the command in terminal:

sh /opt/dropcache-mdn/bin/dropcache.sh --2
/opt/dropcache-mdn/bin/dropcache.sh: line36: can't create /proc/sys/vm/drop_caches: permission denied

Mmmm... Fix this, then I'm gonna give it a try.

This seems to work in terminal with root access.

This is what I got:

...Why don't you just change your VM settings if you do not want any VFS cache?

Also, memory does not work that way.

Re: ProfileMatic & Drop Cache = Infinite memory!!
 

Because I don't know how to, tell me please.
I'm looking for something like fast "re-boot" here mate.

Re: ProfileMatic & Drop Cache = Infinite memory!!
 

Hmm... seems like running as root is required. We're getting into the murky waters of aegis land now. You can try:
