Apoc.cypher.run with cypher from node property runs pretty slow

Hi community,
I've got a weird problem using apoc.cypher.run. When I pass the cypher variable it runs as expected within a few ms. But matching a node and using passing a "cypher-property" to the procedure slows it down to nearly 5 sec. Even if I use a variable with node{.*} or with node.cypher. Any clues about it?
Kind regards

Can you show an example?
