CF8 can create 1000 simple objects in about 100ms on my laptop. Creating them via ColdSpring takes about 4800ms so I'm not sure I'd class that as "a tiny bit slower"... If you're only creating one or two transients per request with ColdSpring then it's a small per-request overhead. FWIW, the overhead of duplicate() is close to ColdSpring/LightWire: Simple Create: 62ms Simple Duplicate: 3814ms Create/Init: 96ms Duplicate/Init: 3985ms Create CS Factory: 64ms CS Create First Bean: 16ms CS Create Without First Call: 4775ms Create LW Factory: 4ms LW Create First Bean: 4ms LW Create Without First Call: 4226ms CS/LW auto-call the init() so I compared Create/Init against CS/LW. I separated out the first getBean() call since that always has more overhead. I'm pasting the code in below in case anyone wants to try it on CF7.
