Is there a way to measure the performance of 3D acceleration, java applets, firefox scrolling etc. with a tool and compare it with lets say a windows OS or other users having almost the same hardware? Maybe it is a setup issue where some fundamental drivers are missing or something?

  • firefox is a quite slow browser you should try google chrome. If you want to see how uch each program is using you can try htop. sudo apt-get install htop copy that exact code and paste into a terminal.

Even when this question is related to software issues you may wish to give a try to HardInfo, System profiler and benchmark, which will allow you to perform several benchmarks in order to gather information of your system and allows you to perform comparisons with other systems.

Linux should run with a considerable ease, the applications that you refer, unless the hardware is reaching its limits.

Most of the times a big memory size isn't enough if the memory speed doesn't fit your need for speed. Hard disk drives should be fast enough and facing no issues and generally: The system should be in good condition.

You don't lose anything giving this a try and may find something that would give you an idea of how is your system handling the physical resources.

Reach HardInfo at: http://hardinfo.berlios.de/HomePage

Here is a screenshot of my CPU Blowfish benchmark with two comparisons.

Additionally you can use a system monitor tool, like Conky or GkrellM in order to see your system's performance when attempting to run one of these applications. This won't fix your issues but will give you a clue on where to start.

I prefer to use GKrellM, so here is a screenshot of my system being monitored by this tool:

Here is a screenshot of Conky (from their site) featuring processes monitoring:

And when writing all this stuff I got a bulb turned on over my head, and I think that you should check what running processes are giving you problems when attempting to do what you wish. I mean: there can be a running process which can be requesting lots of processor or memory and this can cause your other applications to have problems.

Check this out in System Monitor: System/Administration/System Monitor. In the next screenshot you can see my google chrome demanding 122 MiB of the physical memory.

Who knows? you try it and let's see what happen. The more information you gather, the easier to find the solution.

Good luck!


I am afraid, what you are facing is typical of Linux systems, and linux itself is not to blame for this. I would try to answer this one-by-one.

  1. Firefox scrolling has always been slow on linux to start with. Things have gotten better with firefox 4, but its still slow compared to chrome or opera. You can try installing the " yet another smooth scrolling extension" for firefox. This will improve performance. The Link is given below https://addons.mozilla.org/en-US/firefox/addon/yet-another-smooth-scrolling/

  2. Java is notoriously slow on many systems. Even on windows, where it is heavily optimised, performance is dismal. 64 bit java is very messy.

  3. Yes the comparison is very much unfair, as you are running a pure windows game using an emulator. I am sure running a native linux game with a proprietary driver will give a good result.

For measuring system performance, Try the phoronix test suite, which is choc full of tools for benchmarking.

  • Hi tinhed, thx for your answer. I am running the phoronix test suide right now. Only one slight remark: wine = "wine is not an emulator" ;) And thx for the advice with chrome. The difference is immense!

Considering the lag in scrolling in Firefox my first guess is that you lack the necessary drivers for your graphics card. You should try from the menu System -> Administration -> Additional Drivers. And check if there is anything for you.

Firing up a terminal and hit

java -version

to find out which vm is installed in your computer. Try installing the sun-java6-jre.

Give also a try,

sudo apt-get install nvidia-current
  • Hi Chris, thx for your suggestions. To answer your questions: - Additional Drivers are installed - java version: java version "1.6.0_20" OpenJDK Runtime Environment (IcedTea6 1.9. (6b20-1.9.5-0ubuntu1) OpenJDK Server VM (build 19.0-b09, mixed mode) - issuing the command: sudo apt-get install nvidia-current: nvidia-current is already the newest version. So everything seems to be in order doesn't it?

My scrolling problems with Firefox disappeared when I disabled Firefox Sync, and went with the bindwood sync from Ubuntu! If you have both Bindwood and Firefox Sync enabled at the same time it causes all kinds of problems.
