This is a bug to track data and patches to make Mac startup performance better.
On my G3 450MHz machine (midrange these days), startup breaks down roughly like this: start of main() to the time we show the first window is about 9.5 secs on a warm start. main() to nsAppShellService::Run is about 5.8 secs, which breaks down as: (indentation indicates child routine times) NS_InitXPCOM2 0.61 secs Loading XPT files 0.46 Spinning in NSPR idle thread 0.42 (no dlls are loaded during this time) InstallGlobalLocal 0.86 secs Reading prefs files 0.29 AddToCompositeDataSource 0.35 (we load 6 dlls during this time, which takes 0.24 secs total) InitializeProfileService 0.86 secs Getting appShellService 0.08 SetCurrentProfile 0.77 Getting observer service 0.07 Observer notifiers 0.69 Reading user prefs 0.06 Chrome registry Observe 0.63 AddToCompositeDataSource 0.10 nsChromeRegistry::FlushCaches (3 dll loads) 0.32 4 LoadStyleSheet calls 0.19 VerifyPSMAbsentOrSane 1.16 secs InitializeNSS 1.02 (not broken down) CreateHiddenWindow 1.13 secs (not broken down) Of that 5.8 secs spend before we get to nsAppShellService::Run(), about 1 second is spent in library loading. 0.38 secs are spent in the NPR idle routine.

This bug is targeted at a Mac classic platform/OS, which is no longer supported by mozilla.org. Please re-target it to another platform/OS if this bug applies there as well or resolve this bug. I will resolve this bug as WONTFIX in four weeks if no action has been taken. To filter this and similar messages out, please filter for "mac_cla_reorg".
I don't think anyone will work on Mac Classic-startup performance in the future. ;-)
