  • fastfreddie1959 · 1 year ago
    Locate the Preference Name javascript.options.jit.chrome.
    Locate the Preference Name javascript.options.jit.content.

    Neither key exsists in FF 3.1

    Actually, they do. Go to about:config and input the word javascript into the filter. They will be the 4th and 5th preferences listed.

    do you have any technical details or an link about how is this change of speed happening ? I mean, I have enabled both options(the truth is that in 3.1b2pre ----- Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1b2pre) Gecko/20081107 Minefield/3.1b2pre, the option:'javascript.options.jit.content.' is already enabled by default, so just enabled the "....chrome" .I have already seen an important increase at speed, but I need to know how it is achieved.I mean, where's the catch?

    Google JIT or Tracemonkey

    There is no catch

    Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.2a1pre) Gecko/20081208 Minefield/3.2a1pre

    This doesn't seem to make a difference for me, tested using sunspider javascript benchmark.
