I’m experiencing some trouble using content cache component.
The “Content Cache” component consumes resources even if the “Content” input is empty.
Video example: I use a slider that I connect to a “Stream Gate” component. I connect output 1 (empty) to the “Content Cache” component.
When the slider is moved, an empty element is sent to the “Content Cache” component at each position. This creates lag, enough to impact the smoothness of the definition.
The lag is more or less pronounced depending on the time spent on Rhino/grasshopper and can be really disturbing (as you can see in the video).
This is a weird example file. You cannot cache a number and using a button on a stream gate also isn’t a typical application. Why don’t you upload a more realistic definition?
PS: I downloaded your file but I don’t experience the lag you mentioned.

Hello, the point wasn’t sending a number, it was showing that when a “cache content” component is recieving an empty data it takes ressources.
I have bigger definitions, with sliders to design a building and i use “cache content” only once to bake the final state. While I don’t send data to it, mooving the sliders send many “empty” to the “content cache” and it shouldn’t make the definition slower. This exemple just illustrate the issue.

There are some improvements in this area on v8.31.
May I ask how “big” is this model?
How many objects does Rhino report if you do _SelectAll and how many layers do you have at the time the video was recorded?
The changes done in 8.31 should reduce these 15ms to 1-2ms but I’m really curious about this extra delay not reported by the profiler.
