Ubuntu 12.10 Performance Comparison : 64-bit vs 32-bit

It has been known that the X86 64bit architecture outperform 32bit architecture. However, little is known whether 64-bit Ubuntu installation outperforms its 32-bit counterpart significantly as the latter is marked as recommended download from Ubuntu website.

Luckily [Phoronix] had answered these questions for us. In its latest article, [Phoronix] compares the performance between 64-bit Ubuntu installation and 32-bit Ubuntu installation on a Intel Core i5 2520 (4 cores) with 4GB RAM.

Audio File Encoding Performance (less is better)

Server Workload Performance (more is better)

The result concludes that Ubuntu 12.10 64-bit performs better on overall compared to 32-bit, especially on video/audio encoding/decoding tasks. Ubuntu 12.10 also performs better with server workloads.

My thoughts:
Although Canonical still marks Ubuntu 12.10 32-bit as the recommended download. It seems that 64-bit installation offers greater performance even without the advantage of having greater memory. Some might argue that PAE still allows 32-bit Ubuntu to access more than 4GB RAM, PAE access on 32-bit is still significantly slower when compared to 64-bit memory access. Personally, I use Ubuntu 64bit for my development machine as all of my hardware has opensource drivers.

How to remove Amazon Shopping search result from Unity

Hi there, Ubuntu 12.10 Quantal Quetzal is out! However the Dash search functionality includes shopping results retrieved from the internet (namely Amazon), which I personally found annoying.

ubuntu

In order to remove that, just run this command:

[bash]
sudo apt-get remove unity-lens-shopping
[/bash]

This will remove online shopping search suggestions. Your mile may vary, but from my point of view, it does speed-up search result.

Try it!

Compact Grub and Remote Login menu: New features that I love in Ubuntu 12.10 Quantal Quetzal

Those who are keeping up with the updates knows that Ubuntu 12.10 Quantal Quetzal has been released yesterday!

However now I’m going to share two great features that I like about Ubuntu 12.10 Quantal Quetzal.

#1. New GRUB menu that hides old kernel after updates!

Now, GRUB menu always display “Ubuntu” with each kernel update. All previous kernels are grouped together under the “Advanced options for Ubuntu”.

So you get:

Instead of:

This will keep the computer from listing too many kernels on the boot menu, which is messy in itself.

#2. Remote Login option!

Ubuntu Quantal Quetzal allows users to login remotely to Remote Desktop Protocol (RDP) server right from Ubuntu Greeter.

Other Features worth mentioning

  • Linux kernel 3.5
  • LibreOffice 3.6.1.2, featuring menu that can be integrated to Unity menu.

My new Android app development machine – running on Ubuntu Precise

I always wanted a smooth development machine which can run multiple virtual machine (VM) at once, which is a must when testing app that is meant to be portable across different platform. So just before Ramadhan (in July), I bought 8GB RAM and 1TB hdd from a local pc shop and proceed to set-up my development machine.

The machine already has 4GB ram so adding the extra RAM bumped it to 12GB. The machine I was running is an older Intel Core i5, which is decent enough to execute all the VM that is necessarily when developing and testing the app.

 

with all those RAM, seems it’ll be quite a while before I use the swap space again.
