Performance on original iphone

[developersteve]

Hi,

I've built and deployed versions of kit test and my app. Its running
fine. But, its quite slow, is there a way to optimize it? Is anyone
aware of where this kind of issue would be? Is it memory or CPU?

Thanks,

Steve

Hi Steve,
Sorry for the late response, just clearing out my email. This is
mostly a CPU bound problem. The simplest performance improvement is
to reduce the size of your language model. Also, the first time it
performs a recognition it loads the accoustic model and some other
things. If you look at the code you can do that loading before
prompting the user to increase performance. The runtime limitation
is most likely a CPU bound problem, but the initial load is probably a
combination of IO bound and CPU bound.

There are some serious performance improvements available on the
iPhone, but they will take a fair amount of work. This is running on
the ARM processor more or less un-optimized.
