Performance/Achievements Windows Startup

Overview - current achievements for Windows

This page wants to provide information about current achievements regarding improving the cold start up of OpenOffice.org on Windows operating systems. Measurements were done using the Performance Monitor tool from Microsoft.

Low-end system with limited memory

Test machine

• Notebook
• 1,8 GHz Pentium M (Single core)
• 512 MB RAM
• 60GB disk drive
• Windows XP SP3

This is a typical notebook system with plenty of software installed by the notebook manufacturer. Windows reports about 205MB of physical memory available after start up.

Optimization method	Test run 1	Test run 2	Test run 3	Mean
OOO310m9	22,2s	21,6s	22,1s	22,0s (100%)
OOO310m9 (prefetch*)	21,0s	20,7s	21,1s	20,9 (95%)
DEV300m45 (flat+non-rebased**)				(%)
DEV300m45 (flat+non-rebased+prefecth)				(%)

(*) Measurements were done with Windows using the Prefetch feature enabled.
(**) Current optimizations for a better cold start up performance

Medium range system with plenty of memory

• Desktop computer
• Opteron 175 (Dual core) 2,2Ghz
• 4 GB RAM
• Deskstar 7K250 160GB 8MB Cache
• Windows Vista Ultimate 32-Bit (Super Fetch disabled)
