Performance in Web Browsers
If you use Apple's Safari browser, please upgrade to version 4, as it fixes some issues that impact this project, and is much faster than previous releases.
If you don't use Apple's Safari browser, please consider using it, as it is a decimal order of magnitude faster than IE8 and Opera (<10), 2-3x faster than Google Chrome (as of 3.0 alpha), and 4-5x faster than the Firefox 3.5 series, for nearly all JavaScript programs; not just JSMeta.
Instructions are available here for building the jsc.exe JavaScript interpreter, a part of the WebKit project.
