From your comments, I assume you've given up on a traditional (scatter) install, which is not recommended on tinycore.
Many users make the mistake of downloading all their extensions to load "onboot". If you only set a few extensions "onboot" and set the ones you use occasionally "ondemand", tinycore will boot a lot quicker.
In tinycore's early days some time was spent to optimise the creation of extension symlinks, but any patch suggestions that make things quicker would be gratefully received.
