I separated the list of libraries loaded by Firefox into three groups: same libraries as Safari, other system frameworks, custom libraries. | |||
What needs to be done to make Firefox use the dynamic library shared cache as aggressively as Safari? | What needs to be done to make Firefox use the dynamic library shared cache as aggressively as Safari? | ||
Another puzzling bit involves the difference between Safari libraries loaded by dyld (above) and the list of libraries that Safari is linked against, e.g. | |||
<pre> | |||
otool -L /Applications/Safari.app/Contents/MacOS/Safari | |||
/System/Library/PrivateFrameworks/CrashReporterSupport.framework/Versions/A/CrashReporterSupport | |||

Does Safari lazily loading some frameworks? Why do I see OpenGL initializers run when I set ''DYLD_PRINT_INITIALIZERS'' then? The OpenGL framework does not appear to be loaded when Safari starts (dyld output above). | |||
For the sake of comparing, here's the list of libraries that Firefox is linked against | |||
