Why does this help my Titan Memory?

**sc00b4s7eve** · #1 (**permalink**) 07-02-2008, 04:06 AM

I'm running the No2Chem 5067 kitchen w/ a 5MB pagepool. I've been really testing the memory management over the past few weeks only really using Schap's Advance Config: FScache, FS filter cache and glyph cache combos.
I ran across these and thought Looks close to what I'm using, why the hell not. I can always reflash.
Basically... They help... A LOT and it seems it's at the expense of a little battery life. What I'm wondering is why. What are these extra strings doing and are all of them necessary or even functional?

[HKEY_LOCAL_MACHINE\System\StorageManager\FATFS]
"CacheSize"=dword:00001fa0
"EnableCache"=dword:00000001
"BufferSize"=dword:00000100
"DataCacheSize"=dword:00000800
"EnableCacheWarm"=dword:00000001
"EnableDataCacheWarm"=dword:00000001
"EnableFatCacheWarm"=dword:00000001
"EnableWriteBack"=dword:00000001
"Flags"=dword:00010046

[HKEY_LOCAL_MACHINE\System\StorageManager\Filters\f sreplxfilt]
"ReplStoreCacheSize"=dword:00001fa0

I don't know but I would be interested in knowing as well. Since I have the 2100mAh battery, I could live with a more speedy and happy Titan for a little battery loss... I only charge every two to three days anyway

2 or 3 days! That's awesome/ kinda jealous. Gonna have to look into that battery finally.

You think I should ask this in the No2 5067 thread? Seems like not a lot of people get out here to the rest of the site hehe.

The impressive thing is that it manages the cache so tightly.
It actually reclaims almost all the memory it used when I close programs. The only time I see unexplained lost memory (leak) is when I wake up in the morning. Before it seemed to leak all day long.
I only really need to use Oxios for the non-Titan programs like HTC Album.

Two of us do. I am running the same kitchen...

I'll try these hacks tonight and let you know.

Just to put it out in more conventional values, the OPs values are in hexadecimal, these are the same exact values - just in decimal...

The following are dwords in [HKEY_LOCAL_MACHINE\System\StorageManager\FATFS]
"CacheSize"=8096
"EnableCache"=1
"BufferSize"=256
"DataCacheSize"=2048
"EnableCacheWarm"=1
"EnableDataCacheWarm"=1
"EnableFatCacheWarm"=1
"EnableWriteBack"=1
"Flags"=65602

[HKEY_LOCAL_MACHINE\System\StorageManager\Filters\f sreplxfilt]
"ReplStoreCacheSize"=8096

I had only:
The following are dwords in [HKEY_LOCAL_MACHINE\System\StorageManager\FATFS]
"CacheSize"=0
"EnableCache"=1
"Flags"=68

And nothing else in a (i think) stock config in no2 5067 kitch w/ the perf tweaks, I'm gonna try these for a day or so and see what I think before I try out the latest and greastest from no2chem. I'm curious what these are set at in his pre-release2 that just went up?

Alright then. I was skeptical at first. Most memory management tweaks do nothing or just use more memory and make the device speed up, but do not provide any improvement in out of memory errors. The tweaks above (mainly the "CacheSize"=8096 and "ReplStoreCacheSize"=8096" provided a pretty good speed bump (on my Sampsons WM5 Rom with GPS/BT based on No2chems 5067). I turned the "ReplStoreCacheSize"=4096 and saw a decent maintanence of speed with less memory used up. Dropped from 17 megs to about 14-15 megs after running the device for a couple of hours.

But here is where things get interesting. Skyfire, Picsel, opera 9.5... all my memory hog programs (with out of memory errors on No2chem Roms at 15megs) run fine. Memory drops to 4-5 megs on high image intense website, but no out of memory errors yet. These are the first speed tweaks that seem to improve memory handling as reported. WOW the device seems almost perfectly stable. Will continue to test the abilities, but in the single day of testing, works great !!! Highly recommended.

Update:
Better performance and speed when I changed these values.

[HKEY_LOCAL_MACHINE\System\StorageManager\Filters\f sreplxfilt]
"ReplStoreCacheSize"=16194
and
Glyph cache to 64k
I just used Schap's Advanced config to change the glyph cache.

Hey!
What does the glyph cache do or what is it for?
No one seems to know... I even asked on schap's thread!

interesting. I'll give these a whirl and see what happens.
