in reply to object oriented performance

Some overhead, yes. 30% ? Not likely, unless you subscribe to the notion "each method should only be <tiny-number> lines long", which would mean the overhead of each method call is a significant piece of the total RTT.

Also note that its possible to use arrayrefs for your objects, tho you should only use that for "final" classes. Last time I ran a comparison test, arrayref objects were almost 4x faster than hashref objects (assuming the called methods are just stubs).

Update: Ooops!Just recalled, the arrayref tests included member references, I believe thats where the biggest improvement between arrayref v. hashref objects shows up...
