Use the cache node to accelerate the copy-stamp operation.

This technique is useful in cases when it's enough to copy a limited number variations onto many more points.

Put a cache node under the expensive part of the stamped branch and instead of $F use the stamp function in the cache node's index parameter. The stamp value must be an integer and it must fall between start and end. The easiest way to generate a good stamp value is to use the modulo of the template point number, for example $PT % 10 for 10 different stamp values.

After this setup the variations will be cached into ram. Note that you will have to clear the cache manually after parameter changes to the upstream branch.
