I have a problem with my speed in the following example. On the smaller data set it is perfect but I need to run this on a 4,7m record data set. Is there something that I can change or something different that I can try to reduce the building time but get the same result?
Hi, time ago I did something similar, the bucle goes too slow and using peek() with 12 fields, rangemax() and rangemin() improve the loading times. No sure if this can be your case, with this few rows is hard to check differences.
