in thread Question about curious performance of if...elsif block
For those of use who not only remember but actually used them, this sounds like fortran's computed goto statement. However in my case it's not that I want to execute different subs, but rather blocks of code. Can I do the same thing using labels? That really would make it a computed goto. ;)
However I would still like to hear any and all theories about why this curious behavior. The script in question is 'collectl', an opensouce project I released a number of years ago. It's a very light-weight system monitoring tool and am always looking for way to make it even lighter-weight and this feels like an opportunity.
On a different note, my comments about rhel6.2 were wrong. I forgot the VM has <100 processes so I'm actually executing have the number of tests and so the performance improvement over the earlier tests seems as little better but not that much better.
