SWF file size and memory

The runtime memory available to Flash Lite applications running on mobile phones is limited
and might vary among models. Generally, for mobile phones, this limit is not less than 1 MB.
Because Macromedia Professional 8 does not provide a way to check a phone's runtime
memory consumption, Macromedia strongly recommends that you test all content on actual
mobile phones.

Performance optimization

The CPU speed in mobile phones varies among models and is typically much slower than the
CPU speed in current desktop computers. Therefore, it is important to consider application
performance and optimization from the beginning of each project for creating Flash Lite
content created for mobile phones.
