Basically you can gain up to 25% performance simply modifing some text file :)
There are lot of thing to do, to cut down RAM usage, tune the sd card and hack a bit the CPU.
Here the complete list of improvment:
RAM usage: remove not needed services and daemon, change start.elf file
Disk tuning: we use an sdcard so everything is writing/reading from our sdcard will drop our (already very low) performance. There are lot of improvment we can use to minimize the hidden i/o and it can be integrated in the kernel or not. So, we have to remove unecessary log from /etc/rsyslog.conf, change the disk scheduler to deadline, add noatime/relatime, noadirtime, writeback to ext4 partition and use squashfs+aufs as filesystem for /usr
CPU Hack: just change in config.txt the arm_freq, gpu_freq and sdram_freq... at your own risk!!!
