Some complain OpenOffice.org is slow and bloated. With each release there may be dozens of performance improvements, but there are also new features, some of which may slow things down. This the natural balance in software development, but in the end, what is the net effect on performance from one version to the next?
In conclusion, OpenOffice.org is generally getting slower with each release. However, startup performance has made great improvements, the performance losses are relatively small, advances in new computer hardware are more than making up the loses, and OpenOffice.org continues to mature with new features. OpenOffice.org doesn't compel users to upgrade, so you are welcome to continue using older versions.
Profiling an application lets you see what functions are taking up most of the CPU time so you can concentrate your optimization efforts on making the those pieces of code run faster. With sysprof, you can profile all the applications that are running on your machine
To get the most out of sysprof you should also install the debug information for all the applications you wish to profile. Without the debug information you will see only the name of a shared library in the profile information and not be able to tell what functions are taking up the lion's share of time spent in that library.
I’ll try to discover how a 2008 edition of Ubuntu Linux will perform against the 2001-born Windows XP fortified with 7 years of bug-fixing and 3 Service Packs.
To sum-up, I’d say that Windows XP SP3 is a very solid performer and it beats the default Ubuntu in anything related to multi-media processing. This only adds to the misery of Linux in this domain as it still struggles with proprietary codecs and lacks a proper HD support
On the other hand, Ubuntu is a big-time winner in multi-tasking which reflects how well it handles system resources. It also out-performs Windows in hard disk performance thanks to its support for EXT3 file system.
