Editorial As a recent ACM Queue article observes the evolution of computer language is toward later and later binding and evaluation. So while one might quibble about the virtues of Java or the CLI (also known as microsoft.net) it seems inevitable that more and more software will be written for or at least compiled to virtual machines. While this trend has many virtues, not the least of which is compatibility, current implementations have several drawbacks. However, by cleverly incorporating these features into the OS, or at least including support for them, we can overcome these limitations and in some cases even turn them into strengths.

Re: JIT is faster than static compilation

I forgot to add something...

Anything you (or a JIT) might do to optimize a program while it is running is going to require some overhead of it's own. Whether this overhead while outweigh the optimizations is a good question which you need to ask.

Personally, I don't know if it does or not with the current JITs. Perhaps someone else does.

With such optimizations done by hand though, they are "easily" checked and eliminated through a sufficient level of testing. (I'd imagine that a JIT should be capable of doing the same thing automatically.)
