- All files were cached on the local disk. An optimized build of viewer created on 10/16/99 was used.
- Each pecentage is based on an average number gotten from 3 measurement attempts.
- GFX widgets were turned OFF.
- The machine on which these measurements were taken was an NT 4.0 box with 128 MB RAM and 450 MHz CPU.
The raw data used to generate these percentages is available here. You can generate this data by setting MOZ_PERF=1 in your environment and re-building the following directories: mozilla/modules/libutil, mozilla/layout, mozilla/htmlparser, and mozilla/webshell. This currently works on Windows only. I'm going to try to get this working on Unix by today.
