[MOD] CrossBreeder - Entropy Lag Reduce/DNS Speedup/Clean Adblock - Wildfire Themes and Apps

Crossbreeder is an 5in1 package created to make Android devices run faster with less lag and to give a significant performance boost.
Tested and confirmed to give our wildfires a considerable boost. Tested on CM6, CM7, CM9.

all credit goes to idcrisis for creating this package. I'm just sharing this with my fellow buzzers.
what Crossbreeder actually do, QUOTED FROM ORIGINAL POST,
This is a combination of 5 different
key methodologies to improve the
Android experience:
1. It's a big new feature, DNS
caching, parallelising and tether
boost . A lot of the lag in a lot of
apps, apart from the GUI lag, is due
to slow DNS querying, specially on
the mobile network.
CrossBreeder now runs a caching,
parallelising DNS client on the
device. So now most of your DNS
queries will be served from the
cache and if not found, the query
will be sent in in parallel to
multiple DNS servers including the
two Google DNS servers and your
two ISP servers and the quickest
reply will be served to you, hot and
transparent. You can read this
rationale for this approach - http://
ma.ttwagner.com/make-dns-fly-...q-
all-servers/
This speeds up network access and
networked apps, like Browsers of
course, and Tapatalk, Gmail and
thousands of others drastically. And
removes a lot of the lag where it was
due to DNS querying. This will not
increase your network or download
speed but pages will load much
faster.
This will future proof your devices as
more and more apps start using
HTML5 and/or reside completely as
web pages or the like.
CrossBreeder boosts your tethering
connection. Client devices to your
device will take advantage of the
new DNS. Hence their usage is also
improved! In many cases this update
might even fix a broken tethering
feature on your phone. So if your
ROM doesn't have a working
tethering support, you an try and
install this update. It might
magically start working!
CrossBreeder blocks ads and
spyware in an efficient manner by
blocking access to the host. It does
this using a static block list of known
ad sites and behaving as an
authoritative DNS server for these
sites and redirecting them to a
dummy address. CrossBreeder runs a
simple web server serving empty
images and pages, so ads completely
disappear instead of showing an ugly
Page/Image Not found error.
You can update this block list from
an external specialised tool like
Adaway if you need
It also renames any existing /etc/
hosts file on your device. Testing
has proven that keeping a system
wide /etc/hosts file as is used by
most other Ad blocking software
actually slows down your system. So
it is recommended to use this
method instead. Check this out for
the demonstration of the slowdown
and how to test it yourself - http://
forum.xda-developers.com/
show...php?p=41877518
In order to achieve all this DNS
related functionality, CrossBreeder
relies on the excellent open source
utilities - DNRD and Dnsmasq
2. Modulate OS entropy levels for
lag reduction ala Seeder. The whole
OS reads either /dev/random or /
dev/urandom and both need
entropy. However this mod uses a
completely different, lightweight and
efficient random number generator
called Havege . This sharply reduces
cpu consumption and corresponding
battery life loss compared to Seeder.
It also does a better job at keeping
entropy levels high hence your
device is more responsive. It doesn't
run in a CPU intensive loop either.
The extend queue functionality has
also been added to CrossBreeder.
See here for another rationale
favouring Havege compared to Rngd
- ( http://code.google.com/p/csrng/ -
Look for the limitations.)
3. Change kernel parameters
specially the wakeup threshold ones
so read blocks are released instantly
and writes never wake up as we have
an external entropy generator. And a
host of other fail safe and working
tweaks from the community for each
key subsystem. ( one can look
inside /etc/CrossBreeder/
zzCrossBreeder ).
4. Remove /dev/random as it's
blocking . Link it to non-blocking /
dev/urandom. Since /dev/random is
blocking and designed to protect us
from Quantum alien cryptographers
with mathematical certainty and
urandom is non blocking pseudo-
random device that most apps and
OSs are using anyway and with
Haveged running, is as secure
anyway as it's very difficult to empty
the entropy pool faster than Havege
can replenish it. Pre ICS devices
have a lot to gain with this but ICS+
devices show visible gains too.
5. Frandom support (Optional) -
CrossBreeder now supports linking
both your random devices to the
extremely fast alternative - Frandom
( http://billauer.co.il/
frandom.html ). This module is
orders of magnitude (10-50 times)
faster than the standard character
devices ( Check this out - http://
forum.xda-developers.com/
show...&postcount=134 ). The
erandom character device also
installed by Frandom doesn't use up
system entropy at all on top of being
fast. You will need to ask your ROM
developer to develop the kernel
module for you and then place it
in /system/lib/modules.
CrossBreeder will then try and load
it and if successful, make all the
necessary adjustments so that both /
dev/random and /dev/urandom are
pointing to /dev/frandom and /dev/
erandom respectively. The speed
benefits are to be seen to be
believed. But since each ROM
requires a unique kernel module,
this option is left optional ( but
auto detect ). Advanced users can
even try and load the frandom
module built for other kernels if
they don't have one readily available
for their own kernel version using
the Punchmod utility. Read this:

remember to download both Crossbreeder and uninstall ZIP files. it's very unlikely that crossbreeder will cause any problems, but it's better to be prepared.
Feedbacks are welcome

Tested on rempuzzle, change nothing , will test other thing.
And Tested on miui v2.3,it improve the performances.
On aokp v5, it make bootloop when We usés the ROM too long ( without oc ).
On miui v4, improve stability.

well,rempuzzle probably don't need this, since its fast enough as it is now. but it would have been great if this worked.
I think aokp v5 has seeder intergrated, maybe they are conflicting with each other. but crossbreeder says it prevents seeder from executing, so I'm not sure.
anyway thanks for the info

It does. I had that myself when crossbreeder stopped seeder app automatically after having flashed it.

yes, I know it does, I was just guessing a probable cause for the bootloop.
Maybe it's something else, better leave that to devs to look into.

Tested this on DK froyo ROM. It does make a difference.

Updated Attached files to latest version (6.23.13_v2)
If your current Kernel doesn't support Init.d executions, try an app like Universel Init.d

I flashed AOKP v5 and deleted the seeder script from Init.d folder after flashing Crossbreeder, and I did not experience any bootoops while I was using that ROM ( I used it for about 2 weeks)
Does Rempuzzle support Init.d scripts?

Definitely, this mod effects, cm7 becomes smoother.
while coming out of app drawer back to main screen, scrolling has also improved.

Intresting..
Thnx for this m8 Going to try hopefully it will reduce many lags :]

Btw i'm new to this all :] :good:
