Nokia N900 Smartphone Performance Efficient Enhance Optimization Tune-Up Utilities
Introduction
This collection of scripts efficiently optimize and enhance the Nokia N900
smartphone Maemo software platform by optimizing the Linux kernel file I/O subsystem, cpu subsystem, virtual memory
subsystem, network stack and the network card and also this collection of scripts include a simple firewall to stop DDOS, DOS, Spoffing, MITM, Flooding attacks and a traffic-shapping script to group http and ftp network packets over
others and to minimize the network traffic overhead by implementing the Linux iptables kernel module and the Linux iproute kernel module. This script can be considered
as aggressive performance efficient enhance optimization of the Maemo software platform. This script is very easy to install and to uninstall and it is very simple to
use but first off I strongly recommend you to make a backup.
Here's a quick benchmark with a clean device (left) and a modified (right):

@600 mhz 9024 points @850 mhz 11359 points @950 mhz 13162 points Read speed with dd: dd if=/dev/mmcblk0p1 of=/dev/zero bs=512 count=9000000: dd if=/dev/mmcblk1p1 of=/dev/zero bs=512 count=9000000: |
@850 mhz 12934 points @850 mhz 12292 points That's more then 1000 points better or (12934-11359)/12934*100 = 12.177% more performance (112.18%) Read speed with dd: dd if=/dev/mmcblk0p1 of=/dev/zero bs=512 count=9000000: dd if=/dev/mmcblk1p1 of=/dev/zero bs=512 count=9000000 |
Features (random order)
- Offload memory swap with a 2nd swap partition on the external SD-Card (optional). SD-Card partition can be deliver for 8 GB and 16 GB cards.
- Bash 4.2 (more powerful X-Terminal emulation)
- Adds directory-colors to directory in X-Terminal emulation
- Compatible with Swappoluble (edit and change settings)
- simple Firewall (protect against DDOS, DOS, Spoffing, MITM, Flooding)
- Traffic-Shapping
- Cpu subsystem tuning
- Network subsystem tuning
- Virtual memory subsystem tuning
- Massive interactivity improvement of File I/O subsystem under high load
- libmlockall to lock the RAM of the X-Server (not letting it swapped in critical situations)
- Compatible with kernel-power (v46, v47)
- Sqlite-Optimizer (vaccum defragmentation of every single unencrypted sqlite database in the root folder, especially useful for microb, modest and tracker)
- Microb performance optimization custom configuration script (user.js)
- pulseaudio update
- Control Groups tuning (4lineshack)
- Installation-Windows (control of installation of additional libraries and Sqlite Optimization)
- Fixed DBUS_SESSION_BUS_ADDRESS issue in rootsh
- pin rootsh to stop update of rootsh
- blacklist joydev module
- un-nice xorg
- disable access control xorg
- Re-Nice of important apps

Installation-Guide
1. Installation
- Tune-Up is Nagware. First off you want to download a demo
version. This demo is not limited in any way but there is a very small yellow notification (banner, pop-up window) to remind you to give a
small donation when you think this app is useful and if you like it. To get the full version you must be a member of Paypal and click
this Paypal button:
and
after I receive your money I will send you the full app.
- Bugfix: If you have this error: dpkg: error processing /home/user/MyDocs/n900-tune-up_0.0.1.deb (--install): unable to create `usr/local/sbin/cgroup_clean': No such file or directory Removing `diversion of /usr/share/policy/etc/rx51/syspart.conf to /usr/share/policy/etc/rx51/syspart.conf.distrib by n900-tune-up' then in rootsh type mkdir -p /usr/local/sbin and then reinstall the app.
- Bugfix: Control groups fix.
- Install the Debian package (.deb) with the default File-Manager
- Press the Tune-Up-Button in the application homescreen menu
- Press the Install-Libs-Button in the application main window
- Recommend: Press the Partition SD-Card-Button in the application main window (make sure you have a backup of the external SD-Card, and press O.k. if you want to format and erase the entire sd-card and divide it into 2 partitions with an additional 2nd swap partition to offload memory swap)
- Recommend: Press the SQLite-Optimizer-Button in the application main window (vaccum defragmentation of every single unencrypted sqlite database recursivley found in the root folder and below, this is especially useful for microb, modest and tracker)
- If all problems are solved then please press the power button to reboot and enable the changes!
2. Remove
- Press the Tune-Up-Button in the application homescreen menu
- Press the Uninstall-Button in the application Tune-Up main window
- If all problems are solved then please press the power button to reboot and enable the changes!
3. Benchmark
- You want to test microb by visiting 1, 2, 3, 4, 5.
- Disk benchmark for internal Memory: dd if=/dev/mmcblk0p1 of=/dev/zero bs=512 count=9000000
- Disk benchmark for SD-Card: dd if=/dev/mmcblk1p1 of=/dev/zero bs=512 count=9000000
