Subject: Some buffer testing

Some buffer testing

Hello fellow Rockboxers!

Since we've been curious about the buffer usage differences between
Rockbox and the Archos' stock firmware for quite a while, I did some testing.

The file used is a CBR 192 kbit (44.1kHz) (fyi, "The memory of trees", by Enya).

The three values are when the disk reads are occuring (except from the first,
which is, as always at 0:00 ^_^)

1:13 2:21 3:29 rbox (old bitswap)
1:11 2:21 3:29 rbox (new bitswap)
0:59 2:00 3:01 archos 1.27d

So what does this mean? Well, basically Rockbox has about 20% more buffer
capacity than the archos stock firmware (at least, the 1.27d version).

I guess there still are a trick or two to get some additional memory;
cutting the games, gadgets etc.

I don't know about you, but I was quite surprised by the buffer difference!

Keep rockin' !!!
