Seeder


Lag reduction for ROOT USERS ONLY!


Many Android tasks run slower than they should for one simple, yet not-so-obvious reason: they consume large amounts of random data from a limited source. Random data is used to generate session keys and unique identifiers, in SSL and wifi, while starting processes, and during inter-process communication.

This data (entropy) runs out frequently, and that causes processes reading from the blocking device (if any) to temporarily stop responding (lag). These processes cannot continue until the Linux kernel repopulates the entropy pool, which takes time. In addition, input events are pulled from the user interface (to refill the pool), which may also contribute to the problem.

Seeder is a service for root users. It assists the kernel in "topping off" the entropy pool by re-seeding it with data from the non-blocking (high performance) random device. Optionally, it can also help alleviate MMC I/O contention by extending the I/O queue, allowing the I/O scheduler to make better decisions, and combine more writes.

On some devices, applications load significantly faster (particularly large ones like Facebook, Chrome, and Youtube), and task switching becomes effortless. Fewer visual "hiccups" occur.

You MUST be running a rooted device to use this application! If you don't know what this means, Seeder will probably not work on your device!

** Note **

This app does not increase raw performance, but rather eliminates some types of annoying lag (ie. applications briefly freezing, jerky scrolling, delays returning to the home screen, etc). The effect seems to be more noticeable the longer the device has been running prior to activating the RNG service.

Google's efforts to optimize newer builds of Android have been substantial, and Seeder has less effect on Android 4.0+ (though many users still report improvement).

Bug reports are greatly appreciated. If you have any trouble with the application, please send an email before leaving a review. If during testing you find that Seeder does not noticeably reduce lag on your device, please email me for a refund!

Recent changes:
New RNG performance profiles: Light / Moderate / Aggressive (controls RNG seeding frequency). Moderate and aggressive modes may slightly increase battery usage if suspend-on-sleep is disabled.

I/O queue extension increases MMC request queue size and expiry period, which helps reduce lag under heavy I/O.

v2.0.0
- NEW: I/O queue extension
- NEW: RNG power-saving control
- NEW: RNG service performance profiles
- FIXED: Root detection fails on some devices

Good I immediately noticed a difference on my N5. I wish I'd known about this app sooner.

Seems great so far. Seems great and I notice the lag is gone. Can this hurt or overheat my phone or anything? Worried about that.

Doesn't work Does nothing but drain the battery.

No difference I haven't noticed any changes or improvements. It would have been better to have a trial version plus. It also hasn't requested root permission in SuperSu.
