Relatively, as well as in many to most cases absolutely.
Do the math. ...
Hardware speeds have improved and costs decreased dramatically. Software
has become bloated and slow because the producers have been largely focused
on providing more features that users want. An effective software strategy is:
1. make it work
2. make it beautiful
3. if necessary, make it faster.
If you make the effort to clean up your working code, it will generally be
more robust and efficient. Unfortunately, most projects get stuck at step
1, because there is always pressure for another feature. Moore's Law and
faster clock speeds have provided a free ride that allowed developers to get
away with this. Heat dissipation and I/O bottlenecks have begun to render
this approach ineffective and more parallelism at the hardware level is
beginning to appear. This may be an opportunity for J and friends.
