Re: [xmlvm-users] One small XMLVM benchmark

[Panayotis K. <pan...@pa...>]

What if you turn on optimizations for both test cases?

If one supports full optimizations (and is much more faster) than the other
- although it might sound unfair - the final result is that one is faster
and the other is not.
At the end of the day, nobody cares about all the transformations the code
has to pass - the only important thing is the final execution speed.
