Yes

*sigh* What constraints on optimization to you have?

• More CPUs/bigger hardware
• Threading
• Client Server (Message to other machine that runs program that performs operations on a bigger box.)
• Dropping to C for intensive operations. (Using XS to wrap the C into a callable perl function.)
• Optimizing assignments (Only assign a value when necessary.)
• Optimize loop size (Only loop the number of times necessary.)

Any and all of these are possible ways to optimize your program. Which ones are possible in your environment?
