I'm also looking at boot time optimizations on an OMAP. In my case it's a 3530, running at 600 MHZ, and I'm getting numbers similar to yours. But I'm doing crufty stuff like using an NFS root filesystem - so my numbers are probably pretty bogus. But I still don't see how the Nexus One would be getting only 2 seconds apiece for these operations. (I have one, maybe I'll have to do a comparison myself.) I'm very interested in optimizing the class preloading and scanning, as I had previously identified these as problem areas. Maybe we can compare notes? Dianne mentioned that some others had tried to optimize these phases, and possibly ended up causing bugs. Does anyone have experience with this that they can share? -- Tim ============================= Tim Bird Architecture Group Chair, CE Linux Forum Senior Staff Engineer, Sony Network Entertainment ============================= -- unsubscribe: [email protected] website: http://groups.google.com/group/android-porting
