Simple functions with a single input and output in a field network like data-type conversion can be around twice as fast in some cases ( 67c42e7f034aad).In a simple test with the set position node, the improvement to runtime was 1.4x with 10% of points selected, and 2.5x with 90% of points selected.

Selection inputs are now faster in general as the field system can prepare the data for nodes more efficiently ( d3a1e9cbb92cca).Many function nodes with more inputs like Map Range, Combine XYZ, and Random Value are 2-4x faster in common cases ( ae94e36cfb2f3b).A complete list of the updated nodes can be found here.Updating the Realize Instances improves its performance by 2-3x, especially with many small curves ( 6c6f591f909a02).The performance of the Resample Curves improved by roughly 6x when sampling many small poly curves ( 60a6fbf5b59911).The Curve to Mesh node can be 4-5x faster for inputs with millions of curves ( 7484f274dcdc90).The Mesh to Curve node has improved performance, with 10x improvements possible when many curves are created ( 901a03725ed581).Updating the Endpoint Selection node resulted in an observed 13x performance improvement combined with the Set Position node ( 471f27d66bd7).Many curve nodes have been ported to a new data-block, which significantly improves performance with many curves.
