Yes, so WikiServer  ( http://www.mobilewikiserver.com ) is an image file of 10.5 MB.
As startup only 4.5 MB of OOPS memory is faulted in, and about 700K of memory is altered, which reduces initial memory use by 6MB and reduces the startup time by 3+ seconds. Given the slow speed of the iPhone, and the fact I've a 64MB limit, 6MB is a lot, and 3 seconds is welcome. Unfortunately a full GC will fault all that 10.5 MB in, however by doing some GC tuning one can avoid a full GC until things are quite stressed.
Wouldn't a VW-like PermSpace reduce the burden? Nicolas
