How can I make my hacked WPDN run faster? I have a white Pandigital Novel that I hacked to run Android 2.1.  Is there any way I can make it and the apps it runs go faster?  It's already overclocked to 800Mhz and I have no home screen shortcuts.  Is there anything else I can do?
Using JIT (Just In Time) compiler (e.g. installing Froyo, Gingerbread, or "Frozen Eclair") will typically increase CPU-bound processes by 3-5 times.

If your device use FAT, RFS, or NTFS filesystem, your device might be faster by converting to ext2/ext3/ext4 filesystem. However, if you want to prolong the lifetime of your internal memory, use YAFFS2 filesystem.
