Overview - current achievements for Windows (cold start up)
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.
Netbook class
Test machine
- Netbook
- 1,6 GHz Intel Atom (Single core/hyperthreading)
- 1 GB RAM
- ???
- Windows XP Home
Low-end system with limited memory
Test machine
- Notebook
- 1,8 GHz Pentium M (Single core)
- 512 MB RAM
- Toshiba MK6026GAX 60 GB, 2.5" - 5400rpm - UDMA100 - 16MB Cache
- Windows XP Professional 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. Trashing couldn't be noticed during the cold start up tests, even when using Process Monitor for logging.
| 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 | 20,9s (95%) |
| DEV300m45 (flat+non-rebased**) | 16,9s | 16,2s | 16,5s | 16,5s (75%) |
| DEV300m45 (flat+non-rebased+prefetch) | 16,4s | 16,5s | 16,3s | 16,4s (74%) |
(*) 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
Test machine
- Desktop computer
- Opteron 175 2,2Ghz (Dual core)
- 4 GB RAM
- Deskstar 7K250 160GB 8MB Cache
- Windows Vista Ultimate 32-Bit (Super Fetch disabled)
| Optimization method | Test run 1 | Test run 2 | Test run 3 | Test run 4 | Test run 5 | Mean |
|---|---|---|---|---|---|---|
| OOO310m9 | 16,1s | 16,1s | 16,4s | 16,2s | 16,2s | 16,2s (100%) |
| OOO310m9 (prefetch) | ||||||
| DEV300m45 (flat+non-rebased) | 9,9s | 11,5s | 11,3s | 11,6s | 10,7s | 11,0s (68%) |
| DEV300m45 (flat+non-rebased+prefecth) |
