Delayed Differential Equations [NDelayDSolve]

I need to integrate a delayed differential equation and experienced the
following problems with NDelayDSolve:

slow integration (10-100 times slower than NDSolve)
warnings about precission, accuracy, ...
warnings about zero residual

Does anybody has experience with NDelayDSolve
and knows how to circumvent this problems?

Is NDelaySolve better?
