OpenOffice: speed up 'boot

I read very often a bit 'all over the complaints of those who would like OpenOffice it introduce more quickly. Many boast or lament optimizations package provided / compiled for GNU / Gentoo, others use the prelinking binaries and libraries.

Honestly, the 'start OpenOffice on any hardware / software is absolutely one of the most brilliant (not that MS Office do better, mind you). [It: p: id = 278230677, j = l, s = s, l = p] in this post I would like to make some observations on a few aspects of the problem: the optimization of the compilation or binary files and the correct system setup operativo.Al nowadays processors that are installed on our desktops or laptops on average have a computational power so high that office applications should literally fly. It happens regularly once the program is launched and we are using.

The real bottleneck is still in the start of 'application. This is due to various reasons, the most important of which is that applications have achieved remarkable in terms of average size Kbytes "spent", which brings us to these arguments:

• a program "biggest" needs more time to be read from the hard disk and loaded into memory, and how now we should know the operations of reading / writing to disk (and subject to RAM) represent the largest brake performance in today's systems;
• a program is the most feature-rich, will be its largest hunger for RAM memory. When you start OpenOffice reserves a variable amount of memory for its purposes (cache, levels of undo, etc ...).

Operating parameters that govern memory management in OpenOffice you can reduce the startup time of the 'application significantly. By default OO reserves than 100Mb of RAM to undo and many more still to be imported object cache. Note that this ram is spent at startup, even though it will not be actually used.

By setting the level of undo for a reasonable fee (eg 10) and using less RAM for the cache memory (5Mb for the cache graphics, 2Mb and 5 for each object as a limit to the number of items) on my laptop (Intel Pentium M 1.4 Ghz, ATA100 drive) OpenOffice starts in less than 1.5 seconds, while loading a spreadsheet from a Samba share I need about 2 seconds. I verified this performance in the most varied operating environments (processors and disks, Windows, Debian, Ubuntu, Fedora).
