If the amount of water released is 6 litres then I must have chosen the wrong size cistern.
The amount of water is inadequate for the big job and we end up flushing twice to achieve what we expected the first flushing to do. This appears to be wrong on two counts.
First, the 6 litre of water, if it is not adequate for a successful flushing, surely the manufacturers would have gone for a higher minimum.
Second, the cistern does not release more than about 50% of the contents. The previous cistern was also a 6 litre one without the problems of the new one.

If you push-and-hold the handle instead of push-and-release, does that increase the flush?
Were there any instructions with the cistern/syphon about dual flush?
You might think about a Flapper Valve instead of a syphon, gives a good flush, though this will mean taking the cistern off again to fit.

Push-and-hold method did not make any difference. It does not appear to have this facility.
I am ashamed to admit I did not read the instruction thoroughly. Just looked at the diagrams and proceeded, in my excitement of installing my very first cistern. The instructions hit the recycling bin with the packaging.
Please enlighten me a bit about Flapper Valve. Do I have to remove something in the cistern to accommodate this valve?

Yes, you take out the whole old syphon and store it as a spare for ten years, then chuck it away. You fit one of these instead. Hardly any moving parts and gives an unobstructed flow. Is also very quiet.
this kind if the handle is on the front
this kind if there is a push button, or the handle is on the side.
However I think you might do well to ask the cistern supplier if it is dual flush, and how to operate it. I've had syphons with removable plugs and caps to change the flush size.

A thought: You've only replaced the cistern, yes? I think that means that you're entitled to replace it with one with the same flush-volume as the pan was designed for. That may have been 9 litres (even if there was another (6 litre) put in there at some time.) Worth a check.
Another point, often raised - some new pans don't clear their contents at all easily, many designs are just plain bad.
