when I experience a slowdown, I try several other sites that I use as references, having years of 'feel' for their responsiveness. These days it is 'usually' the case that Mudcat is slower. Barring a note from Jeff or Max about it, I would guess that it is internal, and related to memory and cache situations that require the occasional re-boot and tweak. No doubt this could be avoided if Max hit the lottery....*grin*

Remember the problem with the Mars Rovers shortly after they landed? Turned out they stopped working basically because they needed memory cleared for new commands...

I wish I knew for sure....
