I suppose you could try disabling the javascript interpreter, but that'd probably have a marginal impact at best. Unless you have a particularly slow computer, processing javascript code is usually a *fairly* quick deal (No, not "C++" quick, granted). Depends too, of course, on design decisions made by the coder.

While disabling the interpreter would cause your browser to ignore the javascript code, that code would probably still be downloaded, and I'd guess the download itself is what's bottlenecking the works...unless the code is external and hitches a ride via a js include, in which case the include itself won't be executed and the additional code not downloaded.

But (this just occured to me), some dynamic menus depend on images in conjunction with plain-text code. Disabling the interpreter *may* result in fewer images being downloaded, if the image is called from within the script. Could speed things up significantly, if it's the case.

Looking over this post, I'm beginning to realize it's just a longwinded way of saying "I'm not sure." And it's based on the assumption that the menus are driven by client-side scripts (a safe assumption, but not a given).
