Optimized VM(file cache) Control values for Voodoo kernel newest version

Hi,

I just wanted to share my VM settings.

I am using this settings and it is really working very well and snappy, they are almost 100%perfect tuned now;-)

Have fine tuned these over almost 3 weeks have tested all values from lowest to highest values!

VM file cache setting:

*SWP=32(Chose a low value her to use the system memory instead of file buffer from internal file system for applications, that is minimum 10X slower) But you must have enough free ram to get it working good.

This setting makes the phone respond a lot more better!

Don't chose something under 25 because that will have the opposite effect, etc no free ram at all and the phone gets slower and lags a lot.

*VCP=63(It is for cleaning up unused application cache a value about 60 is best here) Have tested it up in about 115 a value like this cleans to much of the cache so it must load for exempel all the content in android market every time and makes the phone slower but frees up resources.

Setting this value to low will make your phone slow and laggy!

*DEC=16(Don't know exactly what this is for but think that it has something to do with the cleaning of unused file buffers on reading sequences)

This one works fine booth with low and high values, but you will get much more stable and faster reading time when you keep it one place between 15 and 20 ;) With this value i get minimum 8mbs on SD card read speed test and maximum so much as 11mbs.

*DWC=19(Don't know exactly what this is for but think that it has something to do with the cleaning of unused file buffers on writing sequences)

This one too works fine booth with low and high values, but you will get much more stable and faster writing time when you keep it one place between 15 and 20 here to ;) With this value i get minimum 5mbs on SD card writing speed test and maximum 9mbs.

*DRA=32(This ratio value tels the system to keep larger file cache in system memory if a higher value) This value makes the phone booth read and write much more stable and speedy, and makes the phone snappier if tuned right!

A value between 30 and 35 is best here, you wont win any speed on setting this higher even if you set it to max value.

The only thing the will happen then is slow down on the read and write speed and hangups when writing and reading things.

*DBR=34(This ratio tels the system to clean up large dirty pages i think)

This value also has something with the stability of the phone when writing and reading files, like the value above.

Keep this to in the range of 30 to 35.

But it works best on 34 have i figured out:)

Setting all of the above settings as i have described here has almost tripled the speed on my phone in some situations, and has also made the phone boot up ready in 50%less time. So it uses 30secounds less time before it is ready when cold rebooting it.

And the gaming performance is incredible also the performance in bigger programs:D

And for those that also wants my low application memory settings here they are:

FA=10MB

VA=15MB

SS=25MB

HA=45MB

CP=50MB

EA=70MB

These memory settings are final and optimal for my phone :-)

Also setting these values makes your phone faster and more responsive then before.

I am using a custom kernel Voodo lag fix newest version so i have 40mb more ram then normal on this phone, so if you are not running this kernel you may have to lower these settings a little bit to keep the phone smooth and stable.

My phone is very responsive and stable with these memory settings :-)

Hope my values helps someone with choosing right values and explains some what they are for.

I will keep updating this post if i find out that some of the values isn't perfect tuned, i can say that the last two values(DRA and DBR) are optimized completely to the limit.

And all the other values aren't far away from that to;)

And BTW don't be afraid to ask me if you have questions to any of the above:)
